I tried it on surfaces of different thicknesses and it fits very well. It rotates and greatly facilitates proper hand support, especially during many hours on the computer.

It won't last forever, but it helped me a lot with the problem that had developed in my hand. Now my hand doesn't get tired, nor does it hurt!

very convenient. the 3 stars for the build quality. every 6 months or so you have to buy one because unfortunately they are not very sturdy

Useless. In 1 week it's already broken and the elbow of the child is childish and girly. Terrible material. It makes you sweat where you touch it. Terrible black! STAY AWAY!!!!

Apart from occasionally creaking, it is very helpful

It raises the wrist significantly higher than the desk. You need to have an adjustable desk or chair for them to be functional, otherwise your wrist is in the air.

It has saved me. You can comfortably rest your elbow on it and it doesn't get tired. Plastic but doesn't need anything more. The best for this price

For 5€ each, it's fine. If you get two, then the comfort is doubled accordingly.
It's plastic, obviously it will make plastic sounds when something hits it.
If the angle of the table bothers you, whether it's for a keyboard, mouse, writing, reading, or any other support needed, then it's definitely a solution.
The platform from the screw base underneath comes off immediately and you can put it aside if it bothers you.
The cushion is half a centimeter thick and made of faux leather, it's advisable to put some fabric on it if your hand sweats.

Very good, supports the elbow

Make it a gift for yourself, it's totally worth it! I got it for myself, I got it for my parents, and I've told all my friends who have office jobs to get it.
