I bought this mouse 3 years ago with an expensive price. After some usage mouse started to misbehave. When I click to left and right buttons, It started to click double instead of clicking once. I used this mouse for 2 years in that condition and I couldn’t asked why it behaves that way since I paid really much money for it. I think I was little bit afraid to buy another one after paying that much money. It really hurts. When I was playing games or making some design in my computer, some unwanted double clicks caused that my works are gone since I wasn’t achieve to save my progress and I don’t know how many times I hit that mouse to table because it made me very mad and angry like hell.
