In general, you can divide them into two categories. I upgraded to a newer model (with a black wheel). The original model (white wheel; side rubber band) garnered the vast majority of the rave reviews. The latest update is far worse. This X-718FB mouse is annoying after using an A4tech WOP-49 (145 in 2022) for seven years. I'm going to have a look at Logitech and Bloody. The pluses: Plus Cost + 5 Buttons + Third Shot Button + Oscar (with everything that it entails in terms of macros and button programming) + DPi Switching During Game (With Light Indicator) + Dependable (Hurray still going strong after more than a year.) Reasons to dislike: Rather from being a pleasant, tactile surface, the coating is grossly abrasive and irritating. Thick, non-elastic cord (gets in the way of productivity).
