i cant say anything about the g500, but i freaking love my 2013 deathadder. I got it on sale for around 40$, and it has really improved my gaming. (over a microsoft basic mouse lol) anyway the click is springy, its ultra comfortable with claw or palm grip. the mouse is comfortable even after extended hours of use. It looks really nice with my green/black theme. As for durability, the product has had no issues after 4 months of daily use. It is build well, and feels sturdy. It is somewhat light, but i prefer it that way. Also its really customizable.
theres my rant lol
