OCC has published a review on the Evercool Booster Cool Wrist Pad

The woes from gaming mostly translated over to the general computer use as well, although the wrist pinning problem was not as evident, due to the Booster gripping my wrist very close to my hand. However, there was a new issue that presented itself, which was that going between using the keyboard and using the mouse, meant I had to make sure to drop my wrist in the exact correct spot to avoid landing on top of one of the fans. Also, a high pitched fan noise was noticeable as I no longer had gaming headphones blaring gunshots to cover up the fan noise. Again, this was not a very good experience.
