Waterproof, fast, wont chop, light, takes c02, pretty good air.
Cons are that it'll need a new barrel like the others. thats the only one I can think of at that price. Its just a vibe. Great little thing.
Vibe & SP-1 are 2 markers that are the same in every way except the body they're in. SP-1 is marketed towards the woodsball/milsim crows, Vibe towards the speedball crowd. But identical markers inside.
