Some new Omron switches to replace the worn out ones in my mouse, was double clicking all the time and really annoying. Got the blue dot ones that are supposed to last like 20 million clicks. The left click stopped working after around 100, heh. It's okay though, I got a pack of 5 for like $8 so I swapped it out again and it's working okay. Annoyingly, the resistance is a little less than the old switches so I keep accidentally right clicking just from resting my fingers on the mouse, but I'm sure I'll get used to it. It's really nice being able to highlight words on the first attempt again, though.
