The way I hold my mouse, the heel of my palm rests on the mouse pad. Normally it's fine, but when I'm on my PC for extended periods, it tends to get sore. I've tried different pads with the wrist rest built in, using gel, foam, etc. I've never liked them because they changed how I wanted to hold my mouse, got in the way, and tended to cause my hand to go numb after periods of extended use. I imagined a normal mouse pad that just happened to be made out of memory foam so that where my palm rested on it, it would just sink in and not get sore. I really didn't expect to find something like that, but here it is. Almost exactly what I wanted. I imagined a square,level memory foam pad.....but this is close enough.....probably better. I can hold my mouse the way I want, no wrist rest getting in the way, and my palm no longer gets sore from resting on a hard surface.

I've been using Pro-B now for two months and I definitely notice a difference. No infections, less irritation during menstruation etc. and I just feel cleaner and fresher -- everything is just 'better' in that area now. I'm very glad I started using them. They are also about $10 cheaper here on Amazon than they are at my local drug store. Bonus!
