yeah its just a little bothering when your 50$ lasts for a month only... and its not like the market would be flooded with decent or even ok mice nowadays to have a variety to pick from
i took apart my ie3 and the actual contact box and flattened the copper part, and that fixed the issue. once you figure out how its held in place, it's pretty easy. i wish i tried this before, i had to get rid of two ie3s before.
