I've narrowed my search down to 2 ego style VV batteries I like, but I'm stuck at which one? When it comes to mah the GS eGo twist II VV 2200mah wins over the Tesla Spider II VV 1300mah. Both are in the same style and price range I like, but where I'm stuck at is which is better quality, Which will last? Tesla is a name most know well where GS isn't so I turn to you my ECF friends to help me choose.
