Wireless ergonomic mouse (Thatto Heath WA9)

This is working OK as a mouse but the scroll wheel is a bit flakey so I have replaced it with a new one (of exactly the same make). If you have contemplated getting an ergonomic mouse but aren't sure whether it would work for you, this gives you a chance to try one out without spending the money to buy something you may not like.
