From here, you should be able to do your repairs on the internals.
Interesting thing to note: Logitech switched some of their higher-end mice to high-quality Omron switches. But this, being a $12-ish mouse, seems to use microswitches from Himake. The actuation force feels noticeably higher vs Omron switches. Durability is up for testing and debate. I personally haven't owned this mouse long enough to tell.
I like how it was screwless and didn't have any adhesives. It makes it really easy to put back together and it means there are fewer things to lose or keep track of.
