What do you think of a 200FPS airsoft M16?

I am a gun enthusiast and i enjoy having airsoft battles with my friends. So i bought on ebay for 27 bucks a M16 electric Rifle. The add says that it shoots 200 FPS, which i heard is very marginal. and llater in the add it said that the gun shot very fast and furious. What do you guys think of it?
