… this ergonomic mouse by Jelly Comb…
… for years i had been trying all kinds of mousing solutions because of pain in my mousing arm and shoulder… for a long time i did mixtures, switching from traditional mouse to track ball and back again periodically in an attempt to use different muscles… this helped, but i was never completely pain free… then i bought this mouse… after several months of use, i was pain free… completely… i have been using the mouse for a couple of years now… the mousing arm pain has never returned, no matter how much time i spend at the computer… your mileage may vary, but for me, this is a thing that works…
