I have been using the mousepad daily at work for about 4 months.The mousepad looks really nice, doesn't smell funny and I don't have any issues about size.Howvever, I still get pain in my wrist and find the only way to get rid of it is to change the side I'm using the mouse on. Previously at work I had a joystick looking mouse (so your wrist in in a totally different position)3M Ergonomic Mouse, Optical, USB/PS2 Compatible, Large Size, Black (EM500GPL)- this gave me no pain but is a bit embarrasing to use. I would recommend not buying this product but buying a joystick mouse (couldn't find one when I bought this but I now see Amazon is selling the 3M ergonomic mouse). Latest workplace assessments in NZ don't reccommend using the mousepad with gel rest but the ergonomic mouse.
