Great for those who need an ergonomic mouse. Has helped with my RSI a lot. Would recommend to anyone who has hand issues. Pros: - Very ergonomic, easy on the hand and wrist, doesn't take long to get used to either. - Good size for small hands, and it's light. - The software configuration tool is very good, lots of mapping options. - Good amount of features for the price. Cons: - Build quality does feel a bit flimsy. - DPI could be more precise, but it is all good to play some FPS with.
