It is for me the second copy of this mouse and I am always so pleased. The second copy is not to replace a first failed because even after 2 years of intensive game it still works perfectly. The second copy is actually to equip a second PC. Meanwhile mouse underwent a slight change and the appearance of grip on the right side (the same as on the left mouse) is welcome and strengthens this already taking great hand.
Certainly we did not like the frills on more expensive models (interchangeable weights, etc ....) but it was never a problem for me. 2 programmable buttons fall well under the thumb and the mouse sensitivity is adjustable on the fly.
I highly recommend this product for all intensive or occasional players who want a good mouse on a budget (it is useless to put 100 in a mouse!)
