Is Buff an app that's worth using for gamers?

Free stuff for playing the games you're already playing. Sounds like a good deal indeed. The catch is Buff collects the data from your gameplay to use for analytics, like how often you play and how well you do. It does take a while to earn Buff points though, so don't expect a new free mouse every month.

i was 1 year premium and dont get enought points , after the year i want to use some points and cant login anymore ... no help from buff :/

it also cost u RAM
