This mouse has been discontinued but IMO is the best shape. I personally modded this with a massive 7 foot light weight ORIGINAL paracord & Hyperglide feet. Well looked after . Bid with confidence!!

The black large sizeMousefromBenQ ZOWIEfeatures an ergonomic design for right-handed users. It offers room for wrist movements. The shape of the right side of the mouse is well rounded and allows the user's fingertips to hold/cover the mouse to move smoothly. This mouse has a 3360 sensor.
