I use a easy vape and a pinnacle pro,the easy vape i have is the old style and still works great.I like it so much i just ordered the newer easy vape v5,they get a bad review because of the tilted heating unit but if you raise the back a little its perfect.the pinnicle is ok but what i like is using the whip on the esy vape with the pinncle hydro tube....Its incredible!!
