BONTECErgonomic Arm Rest for Desk, Rotating Wrist Rest Holder with Extendable 342mm Arm, 12kg Load, Adjustable Aluminum Keyboard Wrist Support, Mouse Arm Rest Pad, Black

Fabulous. I could not use my left hand at all to type due to problems with my arm. Now I can use it almost as good as I ever did, and I was a software developer! I can confirm it is simple to install, very easy to adjust, looks good, is very comfortable, and very well made.What I love the most is its adjustability as I am typing; your arm sits so well and snug in the cradle that it moves left to right, forward and backward, just as you may need it to, on the go. Really feels like my arm is floating but fully supported and in control the whole time.My typing is getting faster and more accurate the more I use it and I can sit more relaxed like I used to. Brilliant.

I am really not exaggerating when I say how good this support is. Its strong, study and no assembly required, just attach to your desk and adjust the height to your preference, I have bought gimmicks in the past are supposed to help but none have been as effective or as comfortable as this. It not only gives your arm the support needed but also encourages good posture, I can already feel the benefit on my mouse hand and my RSI is already much improved. Its a brilliant support and really good value for money. I will be buying another for work.

TLDR:Pro's+ Cheaper than the same rebranded products (they're all basically the same)+ 90% made of metal!+ Solid adjustment+ Comfortable+ Easy to installCon's- Knees might hate you if you mount them too close.- Part which cups your arm/elbow is made from plastic and will be the first to break after a while of usage.- Might get clammy after using it for a while depending on the person.The boring writing:Bought these armrests as my ergochair's armrests squeak so much that I had an embarrassing moment in an interview where someone commented on a squeaky chair. :') I also bought them because I can use them for my sit-stand desk while standing too!They work great and I can apply a lot of weight into them, the only point of concern I have for them breaking is the plastic cupping part where your arm goes and I doubt it will, unless you really try to break them.All of it is mostly made of metal, has really nice rubber grippy pads for the mounting mechanism, mounts solid to the desk and swivels nicely, though it is designed to be loose, there's a lot of negative reviews saying it's so easy to move, and that's the point of these armrests, they help you move your arms around for when you need even if you're not in the same sitting position as before, it's adaptable to other people too.For comfort, they are nice, I'm still trying to get used to them. I suffer with hypohydrosis, which means I sweat easily over literally anything such as holding something for a while, and I can feel my elbows getting sweaty quite quickly. I don't know if this is because of the material and how I can feel it compared to other armrests, but it's something I wanted to highlight here for anyone who sweats easily that they will feel slight dampness.The main reason why they aren't 5 stars, is that my main problem with them is that the screws they use to mount it to all sorts of desks is just too big for my custom desk, my desk is 4cm thick and it's just enough to cause the mounting screws to hit my knees while under the desk, it's something I can cope with or fix myself by changing these screws myself, but I had just wished they had slightly smaller mounting screw sizes, by about 2cm or 3cm. They're the type you'd see used in monitor mounting arms and I think they're the same screw used.Overall, great for both sitting and standing, easy to setup and are cozy to use, I like them and I would recommend them to people who have chairs with bad/no armrests.

Very sturdy, you can put your full upper body weight on a pair. I like that it can be moved around so that it follows where your elbows/ forearms are. And it doesn't take up too much space. Although the top section joint is a bit wobbly, it doesn't feel so bad to me, it probably was not designed to be wobbly, but to me it works like a ball joint to fit my movements.

The grip/fastening for the table works great and after over 6 months of use does not give way. The arm is in metal and also feel sturdy. Unsure if the 'joints'/hinges can be tightened as they are the only that may feel a tad 'flimsy' But so far it doesn't feel like it's going to break, more like it'll come loose. A good product that help me rest my arm more comfortably as I work. Definitely something I would recommend

Been experiencing pain the arm when at my computer in work. Purchased this for extra support. Sturdy does the job. The pain has now eased and provides good support for the arm to stop it hanging off the desk. It’s really easy to move the arm while still supported

Easy to attach to desk and adjust on the ratchet mechanism. Soft and doesn't irritate my skin when used all day. Is helping to support elbow and reducing pain.

The product itself is pretty sturdy. However, mounting it will take some adjusting until you get it in the proper location on your desk. If you have any kind of office chair with wheels be ready to reposition your chair each time to be comfortable using the armrest itself.The second joint and the one directly underneath the elbow-rest itself are stiff and you’ll want to apply some lubrication to it like graphite lubricant else the middle joint will get stiff and you’ll end up fighting with the arm to make it bend in the middle.The elbow-rest itself is plastic and is wobbly. I’ve found myself wrestling with getting it to rotate for the same reasons as the middle joint and the fact that this bit is wobbly; there is no screw to tighten but I’m not confident that would solve the issue and I feel it’s not very secure to the rest of the arm itself.Overall it’s “okay” but I wouldn’t recommend it and would probably opt for a support platform of some kind going forward. The only saving grace it has is the ability to raise and lower the rest itself which is very comfortable.
