new mouse, annoying clicking sound
bought another MS optical mouse (the white one with 1 side button on each side) and the left button (the one everyone uses) makes a lot of noise when clicking, like if it was an old mouse. the old one was also a MS optical mouse but didn't make that much of a noise, maybe becuase it was 2+ year old that mechanism got old
also bought a MS trackball optical for another pc, and doesn't make that annoyin noise, the difference of this MS optical to the old one is it's OEM
