The Cell Mate Chastity Cage has cool tech features that show where the future of sex toys may lie, but some red flags keep it from a 5-star review.
Experiment with orgasm control and denial with a physical device that locks up the penis. Preventing full orgasm and any stroking stimulation, a chastity device can be a very-real and very-physical reminder of the power exchange between two people—or even self-control when playing solo.
Verbally requiring your partner to forego orgasms is one thing, but when that requirement includes a physical device around one of their most intimate areas, it has a much-more-serious feel to it.
Essentially, a cock cage like the Cell Mate is used to ensure that the wearer can't access the penis. While the device allows urination, it blocks any other physical sensation to the penis - which, surprisingly, can be extremely erotic to a lot of people!
Especially with power exchange relationships, the wearer of a chastity cage might ask someone else to determine when they, themselves, are allowed to take off the chastity cage. In chastity terms, we call this permission-granter the "keyholder."
Traditionally, a small, physical lock was used to lock the chastity cage onto the penis, and the physical key was handed to the keyholder for safe-keeping (and denial). But hey, traditional doesn't always have to mean "for forever".
Brand new to the market and completely changing the basic "keyholding" dynamic, the Cell Mate is the only chastity device out there that features built-in Bluetooth functionality.
Essentially, much like how the world of teledildonics works, the chastity device can be controlled because it wirelessly connects to an app on your cell phone. When your partner/keyholder downloads the same app and you both agree to the transfer of authority via the app, the two apps communicate with one another to transfer control of the chastity device to the keyholder's app.
With that transfer complete, unless the keyholder uses their app to unlock the device, there is no way for the chastity wearer to unlock the device. Let me make that very clear: it will not unlock at all unless the keyholder chooses to use their app to unlock it.
As you can imagine, a device like this has some concerns—mostly because all of us have used technology that doesn't function exactly how we want it to all of the time. More on that later.
The Cell Mate Initial Connection and Chastity App
In order to get the Cell Mate Chastity Cage on the penis and ready for lock-up, you need to get the CellMate attached to your mobile phone (and its app). The Cell Mate does not lock or function without use of the Cell Mate app, so ensure that your Bluetooth-enabled phone is compatible with the app before purchase. (QIUI app is available on both the Android and iOS store.)
Once you receive the Cell Mate cock cage in the mail, getting it all set-up actually only takes a few seconds. You need to download the app from your phone's app store (there are QR codes in the instruction manual if you want a fast method.)
Sign-up includes use of an email (use one you can regularly access; no fake emails) and password. It optionally allows you to fill out a profile, but its gender options and role identifications are sorely lacking.
When you sign-up, you must agree to (what I assume) are their terms and conditions. However, their terms and conditions are only in Chinese. There is no English translation of their terms on the app. There is no way to use the cage if you don't agree to these terms that you can't read.
(On that note, the QIUI app also wanted access to my location, 24/7, and my photos, videos, and media. I don't see a reason why it needs any of this before I'm interacting with any functions that require it.)
Avoiding all of the discussion around those issues, you then get dropped into connecting the cage. This goes really quickly. Turn on the Bluetooth, touch the button on the front of the Cell Mate, and they find each other. Tell the device whether you're the wearer or the keyholder of that device (you may initially register it as either), and you're good to go.
Now that it's registered to you, you can unlock it and lock it really easily with a large "lock/unlock" button on the device's home screen. It's some very simple stuff, and after a short "whirr" of the locking mechanism, it will move the metal bar that fastens the CellMate penis tube to the locking ring that resides under your testicles. This then allows the cage to be removed.
It's worth noting that the app logs your location and displays it when you lock or unlock the device. It displays this location information (down to the exact suburb city of my metropolis!) next to your username. I am unable to figure out if it displays this information publicly or for any subs whose Cell Mate I'm controlling.
This is a blatant privacy oversight and one that has literally zero bearing on the function of the device. I can come up with no reason that information needs to be gathered nor displayed in order to play with chastity.
Outside of the basic locking and unlocking function, the Cell Mate app provides other ways to play as well. There's a "Timer" function (discussed later). There are also other didn't-translate-well-to-English functions that I'm not entirely sure what they do at first glance.
These functions include:
- Publicity Device
- Launch a Referendum
- Looking for Keymaster by Conditions
- Looking for Keymaster by Robbing (...what?)
If you click on any one of those, it warns that "There are risks. Please choose carefully !!!" So, for the average person with a chastity device attached to their penis, I think that would be enough reason to click "Maybe Later". For the sake of science, though, I delved deeper into these options to try to find some answers.
Here's what the fact-finding mission determined:
- Publicity Device - This appears to make your Cell Mate "public". It does not specify what that means after you toggle it on or why you would ever want to.
- Launch a Referendum - This appears to let you put up a public "Vote If You Want to Lock Me Up" mode. You may choose how long the voting goes and how long each "vote" is worth. I started a poll, but it never popped up the final tally after it was done, so I have no idea what happened after I tried. The device did not lock itself; it's possible I didn't receive any votes.
- Looking for Keymaster by Conditions - This launches a "Keyholder wanted" ad as far as I can tell. You can choose the gender, age, identification, and location of your ideal keyholder. I'm happy to see that it also offers a "Permission Duration" during your sign-up process - though less happy to see that 30, 100, and 365 days are all default options to allow a complete stranger complete access to control something that is unescapable as soon as control is established.
- Looking for Keymaster by Robbing - I still can't figure this one out. It brings up the exact same page options that "Looking for Keyholder by Conditions" did except I need to choose a time for "How Long After You Start Snatching". I really have zero idea what this does.
- Regulator - This is a blank page, and I have yet to figure out what it's supposed to do.
The app's English translation definitely does leave a lot to be desired—and it comes across as generally confusing for a native English speaker. It's possible that the native Chinese app is flawless.
Let's move onto the connection with the chastity device. So far, in all of my subsequent check-ins with the chastity device, it picks up the chastity device's signal within seconds after you press the power button on the front of the Cell Mate. It's impressive how fast it finds the signal, actually.
It's faster than any other electronic I have including my headphones or my fitness watch. So, if you need instant chastity gratification, it has that going for it. Occasionally, when you tell it to lock or unlock, it hangs and requires a restart of the app, though. When you reenter the app, it seems to function as designed again.
If you exit out of the device-specific control, the app also has other functions - including their own social network they're trying to build. You have to agree to the terms if you want to use the "Community"—but those, too, are completely broken with a display of wingdings and other computer gibberish.
This community appears to be the place where all of your "Looking for Keymaster" and "Refendum Voting" things appear. It shows them off to the world at large within their social network.
You may also post your own photos, videos, and text if you're into that. It had a couple of posts an hour each time I stopped in. If you're really into chastity (and people who use the Cell Mate), this could be a good fit for you once you figure out the system.
It is, predictably, mostly filled with male-presenting individuals. In my time using the Cell Mate, I've only seen a single post by someone who is presenting as female.
Can It Be Used Solo?
While I happen to be part of a pair who enjoys chastity, you can enjoy the fun of orgasm denial solo as well. The Cell Mate app includes a timer function for solo use. Using the app, you set a timer for the cage. The cage will not unlock until that timer reaches zero. There is no emergency override or manual key. It will not, at all, unlock until that timer reaches zero.
I recommend you treat that timer very carefully. It could be very easy to assume you want to be orgasm-free for 14 days, so you set the timer to 14 days. However, this means the Cell Mate will not unlock—for any reason—until those 14 days are up. Since you should really remove the chastity device at least once or twice a week for cleaning (of yourself and the device!) you'd need to think ahead and split your 14-day imprisonment into multiple small spurts in order to get the chance to clean yourself and the device.
When selecting the Timer function in the app, you can choose from minutes, hours, days, or months—to any number you want. For multiples reasons (including the fact that QIUI doesn't recommend wearing the device for more than 14 days at a time), I don't like that "months" is even an option. Before the device is entirely locked, you have to choose the time you want, agree to that time, and then agree to that time AGAIN, so it's pretty hard to accidentally select an unwanted time.
Cell Mate Product Details
The Cell Mate includes everything you need to get started with your chastity journey as soon as you open the box. (Since the Cell Mate doesn't need to charge, it can be used right-away unlike most rechargeable sex toys out there). The Cell Mate includes a zinc alloy base ring (in two sizes), the Cell Mate App-Enabled Cock Cage (in the size of your choice), and the User Manual.
If you're new to chastity devices, the instruction manual includes an illustrated guide about how to put on the cage. The Cell Mate's simple design with minimal pieces only requires a couple of steps, so it's easier than most.
To get a good fit for your own anatomy, the Cell Mate is available in two sizes: Regular and Long. Unless you happen to be very long when flaccid, the "Regular" size will work for most bodies. The "Regular" and the "Long" varieties change the length of the tube where the penis fits by 2cm. It does not change the width of the tube, though. In addition, the Cell Mate includes two base rings (a Small and Large) with either size cage. Select the ring that fits your base best when wearing the cage, but you'll receive both rings with your Cell Mate purchase. The following are the measurements for both versions:
Regular Cell Mate Model
Opening Width: 3.5cm
Tip Opening: 0.9cm
Long Cell Mate Model
Opening Width: 3.5cm
Tip Opening: 0.9cm
Ring Size (Same for Regular and Long)
Small - 47mm diameter
Large - 51mm diameter
The Cell Mate device itself is powered by a non-rechargeable battery. This physical battery has a lifespan (eight to 12 months), and the app will allow you to track the percentage of how much battery is left.
When the battery is approaching its final moments, you'll need to exchange the battery for a new battery. It's a CR14200 battery with a 1.25mm connecting interface. If you can't find this battery locally, it can be ordered from QIUI. I recommend starting this process around the 40% battery remaining mark to ensure a smooth transition when your current battery finally dies.
Wearing the Cell Mate Cock Cage
The first thing to note: the Cell Mate cock cage is made of plastic. Inside this plastic tube, there are multiple areas where the cage is not fully sanded down from its construction. They were straight-up sharp on my finger and caused cuts during wear. You may receive a cage that requires sanding down before you're able to safely use it. I know mine will.
Past that, putting the cage on is pretty easy. Unlike most chastity cages, the automated aspect means that cage wearing only requires a couple of steps. Slide the ring underneath the balls and penis, and slide the penis into the tube portion, and connect them together. That's it. I would have liked to see more ring sizes available for purchase - even if only by individual sale.
The two base ring selections are a-okay as a starting point (and it's nice that both are included,) but most chastity manufacturers provide three to six different ring sizes because testicles certainly aren't "two sizes fit most." Getting a good ring fit is vital for getting a comfortable chastity experience.
While we're talking about the fit, let's talk about the Cell Mate. The fit is pretty good —as long as you have a good fit with the rings. The ring needs to be as tight as possible at the base without being painful. This "very snug" ring fit helps keep the device up and in place. Because the Cell Mate has so much tech towards the front-side of the chastity device (unlike any other device,) it tends to "lean forward" much more than any other cage.
That being said, weight-wise, my partner says it's noticeably lighter than stainless steel while being slightly heavier than silicone or plastic cages. I agree with that assessment.
The Cell Mate can definitely be visible under clothing. In suit pants or office wear, it is very-much noticeable—however, you could chalk it up to an "above-average penis size" if you wanted to if someone was staring. Wearing the Cell Mate with tighter underwear (to get the cage closer to the body) and thicker fabrics (like jeans) makes it a lot less visible, though. I'd just be careful if you're wearing it to the office in dress pants.
Speaking of daily wear, the cage allows urination, much better than others. The very-wide, very large slit at the end of the cage can line up perfectly with the urethra for when you need to go.
At the same time, it's worth noting that the Cell Mate is lacking a lot of the "openings" that some cages have for easy cleaning, so the Cell Mate will need to come off more often than most cages as cleaning and rinsing it during a shower is more of a pipedream than a reality.
This is another reason to ensure you time your lock-up periods reasonably within the timer function of the Cell Mate chastity app. Every three or four days, an unlock to clean it all will keep your skin much happier.
Speaking of bathroom needs, it's important to note that the cage causes a very, very downward angle for the penis—more-so than every other cage we own. It's almost straight down.
This will make it very very difficult to use a traditional urinal (in case you were going to try). At the same time, you might want to keep this very-downward curve in mind if you're someone who has very strong connective tissues that want your penis to point far upward. You might experience a bit more discomfort with erections in this cage than with other cages.
Aside from all of that, he wants me to let you know that it's surprisingly comfortable. Aside from the areas we have to sand, the rest of the cage felt comfortable and natural during movement. It didn't feel overly bulky, and it didn't catch on clothing.
He found that it rested really nicely on the thighs when sitting, and it moved well while walking. He felt its presence, but aside from the parts we needed to sand, it wasn't painful or grippy in any way during his day-long chastity period.
On the Femdom side of things, the visual of the Cell Mate can either be a plus or a minus for you. The Cell Mate's black, opaque outside essentially blocks out all view of the penis itself. And by that, I mean all of it. It's almost like the penis entirely disappears.
If you're into that (especially for humiliation purposes), the Cell Mate chastity cage is probably a good fit. If you're into the idea of looking at a dick being locked up in a cage, it doesn't quite provide the same visual - as the dick is oddly missing. To each their own on that one, but it's worth considering when you're looking at purchasing the Cell Mate chastity cage.
How It Works
When you first receive the Cell Mate, it comes locked. In addition to making it impossible to lock yourself in without the proper set-up, it also means that it forces you to register yourself with the app before you're able to play.
So, really, it ensures you're going to be ready to use the cock cage as soon as you're able to get the cage ready for use.
Your first step will be to download the QIUI app from the app store. The QIUI app is available on Apple iOS as well as Android devices. In order to use the online control aspects of the Cell Mate, you'll need an internet collection, and in order to control the cage at all, you'll need a cell phone that's Bluetooth-capable.
