The bouncing on contact switches becomes excessive over time with corrosion and leads to double clicks. Luckily optical button switches are showing up on a lot of mice, and they don't have have to use debouncing, so the problem is non-existent for them.

Logitech has a couple with optical switches, but most of their line is still traditional. I've been using the wired G502 X, which is pretty decent, and there's also a wireless version.

Roccat is mostly optical, Razer is moving that direction, and Steelseries also has a few under the "Prime" name.
