They come in two distinct varieties. One (with a black wheel) was replaced by me. The original model (white wheel, rubber band on the side) garnered the vast majority of the rave reviews. The newest update is a major downgrade. This X-718FB mouse is annoying after 7 years of trouble-free use with an A4tech WOP-49 (cost in 2022: $145). I'm going to check out Logitech and Bloody. Oscar (with all the repercussions: macros, button programming, etc.) + 5 buttons + 3rd shot button + Price + Switching DPi in-game (with light indication) + Dependable (Hurray still going strong after more than a year.) Some drawbacks: It's not a Soft Touch finish; it's a disgustingly harsh one. Thick, non-elastic cord (gets in the way of productivity).
