This beaded wrist rest is made of soft fabric and does not leave your wrist feeling warm(well ventilated). The only complaint would be that the rest seems to be a bit thicker than necessary as I sometimes have trouble typing on the first row of the keyboard.
It is comfortable and provides adequate support and it is also a fun item to fidget with when I am thinking. I wish it was longer though-- it doesn't match the width of my standard-sized laptop.
This support is the most comfotable I have yet found. I've gone through a few--some that are a sort of foam rubber and another that is a glove. None have been perfect but it suffices. It would be helpful if it were longer i.e. stretching from the mouse pad all the way over to the left side of the keyboard.
Just wasn't what I expected. It helps but I'm shopping for a new one already. The wrist rest is not the same length as my keyboard (Razer Widow Ultimate 2016) so I find myself sliding it across my desk while typing.
