After owning several mechanical keyboards I'm very familiar with the company called Cherry. Known for making some of if not the best mechanical keyboard switches in the world. I was looking for a wireless mouse that didn't break the bank and that didn't feel like a cheap throw away in six months mouse. I'm glad to say this is probably the best budget wireless mouse I've ever used. It has minimal but adequate features, with quality materials and buttons/switches. Should last for several years or more.
