Anker vertical ergonomic optical mouse – USB cable compatible, for right handers, hand and joint comfort, 1000/1600 DPI, 5 Buttons.

I have severe nerve damage in C5/C6 vertebra and two herniated discs. The normal mouse position (hand out and flat) caused a high level of nerve pain to the point of not being able to work.Using this mouse in the "handshake" position is a huge relief! While i still get a low level ache i haven't had the extreme attacks of pain that using a standard mouse was causing me.The price is remarkable too - the product is very well made, functions perfectly (and I use a Mac so wasn't expecting all the soft buttons to work properly but they do) and is cheaper than others I looked at by an order of magnitude! I recommend this to ANYONE who has nerve pain stemming from their neck. I cant comment on RSI/Carpel Tunnel because I don't suffer from this but I would imagine it would help those who suffer greatly as well.I really like this brand Anker - I have also bought a set of their bluetooth headphones and those are ridiculously good quality for the money too - brilliant products!
