The Zero Tension Mouse is an ergonomic pointing device designed to keep your hand in a neutral position as you use your computer. According to clinical tests, it’s the only computer mouse that relaxes all 8 muscle groups that cause carpal tunnel syndrome and other overuse injuries.
I finally purchased the Microsoft Natural Ergonomic Keyboard 4000, after some months of dawdling as I waited for it to go on sale (what can I say – I’m frugal). All in all, I like this keyboard a lot. Ergonomically, it’s quite excellent, and I recommend the Microsoft Natural Ergonomic Keyboard 4000 for anyone looking for a solid and attractive ergonomic keyboard.
