This was purchased for my husband. His mouse was going out and he happened to walk by while this was on my screen. He likes the different colors, along with the fact the battery is internal, so it can be used as a wired OR wireless . It has a nice fit for his hand (he is 6ft tall) and easily set up. #RankBoosterReview #Sponsored #(CombatWing https://www.amazon.com/Wireless-Dual-mode-Rechargeable-Adjustable-Breathing/dp/B078NSKFH9
