Logitech MX518 or Logitech G400?

[LunarWolf]

I am looking for a durable mouse usb mouse, one that can last for a few years. I read that logitech mx518 can last like 5 years. On the other hand, it seems Logitech G400 is the successor to MX518. Which should I get? It will mostly be used for surfing the web, assignments, light gaming vs bots.

This is just my 2 cents and i'm not sure what your light gaming means? But if main point is that mouse should last long and not that gaming? Then i think i would forget gaming mouses and just go the as simplest mouse as possible. The more electronic parts and stuff the more reasons to go break
