I was excited to get this mouse after doing a bit of research. I paid a few dollars for it, it's not cheap, but so far it ok. I wanted to take away the pain from my forearms, and it seems to be working. There is a lot of room for improvements that can be made to the mouse, and it also takes some time to get used to using. It is not like a normal mouse, so if you can try it before you buy it, I would recommend that. PB had the best price, and the service was great during 2nd lockdown in Akl.
