Unfortunately, this is the first time I have been disappointed with a Razer product. In 20 days, the material where I rest my left hand started to deteriorate without excessive use. The factory one took 2 years for this to happen. For its price, I find it unacceptable. I will make the effort to contact Razer as well.

I have had it for 4 months and I have to say that it is incredibly convenient, cool, and seems to be of good quality. Now, as far as durability is concerned, time will tell. Finally, I give it 4 stars because it is very, very expensive for this type of product. (I bought it for 50€)

I cut a star because, although for full-size keyboards, it is a bit smaller.
Also, another thing that doesn't suit me 100% is the height. It's good that it's full and soft and fluffy, but then the keyboard, blackwidow v3, feels low because it already has low stands. So I had to put the previous wrist rest that came with the keyboard to rest on the back.

The cooling gel does indeed make a noticeable difference and the exterior material is better compared to the classic wrist rest from Razer keyboards. I bought it to replace the original one on my Ornata. It doesn't easily move, at least on a mousepad, even though it's not magnetic. It also comes with 2 green stickers

As a material category, it is necessary for anyone who uses the keyboard for many hours. Although expensive, I did not regret at all buying it because the gel provides great comfort with the "coolness" it ensures. Be careful before buying it, because obviously it does not fit all keyboards. Measure the height (mainly) and the length (for aesthetic reasons) of your keyboard before purchasing it.
