Pros: Three months in. Easy install, significantly less lag, nothing is crashing...

Cons: None that I could see

Pros: -Reasonable Price -Smooth Scrolling -Moves well on very uneven surfaces

Cons: -Connection stutters often -Very loud clicking -Short battery life -- only lasts about two months for two AAs with moderate use (no gaming, and turned off every night) -Sometimes the mouse's wireless adapter would just stop working inexplicably, even though it has not been touched. (Works again after being reinserted)

Overall Review: Compared to the mouse I replaced (smaller mouse that needed one battery every six-ish months), this is pretty disappointing.There are better mice for the same price.
