i have 2 vamo's i got from a local shop. i was told both are v3's but they are completely different and i would like to know which is which. one is a smooth body thats pressed together. top cap and tube for small battery. the other has a swirl pattern to it and completely unscrews. i have had them for about christmas and the smooth body and fallen a few times and is now coming apart in the middle and tank has popped off when hitting the floor. i took the extension tube, for larger batteries, and screwed it to where the top ring goes on the swirled body then put the ring back on so i can keep it in my pocket and not pop my tank off. really just want to know which is which and if anyone else has had issues with the press fitting on their vamo. using protank 3 with ego beauty ring on swirl body.
