I've tried products to help with my arthritis like glassouse but this was suprisingly more helpful for less than half the price! Something about the way it has you hold your arm feels more natural and less stressing on the body. Though it's still a bit pricy, it's better than countless sessions of physical therapy only for the problem to come back later on!

Excellent build quality. Very functional and responsive. not a good fit for me however, have to reach over it to use keyboard, roller click too sensitive.if you have a unique situation where you cant use a regular mouse this may be an excellent choice for you.

If you go to their website directly they have a newer version called the RollerMouse Pro which is a much sleeker version of anything offered on Amazon!But this version is also really good - best version I've seen, not too wide, wireless, comfortable position of the right click button, soft foam pads (actually softer than the new version of RollerMouse Pro).

Most ergo equipment can take getting used to, but this mouse is worth it.Since you are using a roller bar to control the mouse, you’ll avoid bending your wrist and avoid putting pressure on it.Been using this mouse for 10+ years and I will never use anything else.

I love this mouse - I don't go home with a sore and achy wrist - or thumb - I wish I had this mouse before I had the Carpool Tunnel Surgery on my wrists.
