Cheap, functional mouse with low durability

First of all: This Logitech mouse does what it should. It works, offers three buttons and is easy and precise to use. You will succeed with me even on a polished granite-Mouse Pad for use. The downside, however: Like on other reviewers here, the middle mouse button up her function with me for less than 1 year. She's just a case of very heavy pressure. Obviously here a tick was too much saving which is not very obvious especially in a switch. 0.05 more invenstiert in the parts, it would probably not have happened. An RMA makes in the price of the mouse but also no fun.
