I've used Logitech mice for years, shelling out hundreds of dollars because their only competition seems to be Microsoft and I refuse to have anything to do with Microsoft. I have had nothing but problems with their mice. They work for a time and then they get buggy. Every single one of them. Every single time. I've had two Performance MX mice and one MX Master. Logitech customer support is the absolute worst of any company I have ever had any dealings with. They either ignore you or pretend they're going to help you fix the issue and then disappear. I see they have a new a new $100 MX Master 3 mouse out now. There is no way in hell I'm giving this horrible company another red cent of my hard earned money.
