I bought this mouse in June 2018 and again in December 2018. After 5 or 6 months it begins to periodically stop responding for a second or 2. Like lags in movement for a second. Obviously that isn't ideal but for the price, it's great value for money. You'll buy 2 of these mice a year. The performance (when working lol) is fantastic. Overall, it's a cheap mouse made from cheap parts that work very well but only for a few months. My advice is, buy 2 of these and have one as a back up, then when it goes, plug the other one in and order another one for less than 5 to keep as your back-up.
