Been using vertical (ergonomic) mice for about a year now. Took a little muscle memory retraining but once I got used to it I'll never go back to a standard mouse. Much easier on the wrist, more natural position for the hand and wrist.
They make left handed ones also, I mouse left handed.
The best rated one is the Logitech MX Vertical but it's expensive and I'm not sure if they make a left handed one. I'm using Perixx wireless verticals but they have developed some "sticking" and lag so I'm going with a wired version for $12. The Perixx looks just like the Anker mouse shown above.
This is the MX Vertical, it is rechargeable.
