I've never had a mouse this light before! It's lighter than my previous mice and bigger too! It doesn't compromise on structural integrity to make it lighter. It should be able to handle normal use, but I don't know how well it holds when chucked across the room in a fit of rage.
Fits my hand nicely. ATK HUB let's you change mouse settings. Clicks very well. The white looks awesome! I think this was definitely worth it!
