I personally love my vamo. I call it the lightsabre because it is rather big and definitely heavy. It is solid and works very, very, well. The only problem i've encountered was that i didn't realize you couldnt use trustfire protected batteries in it. Only the aw, icr, etc. types.
There is a known problem with the vamo. I encountered it after putting my rsst rba on it and tightened it down too much. It caused the white washer under the center pin to push through. This made the center pin contact the sides and give me a short. The solution. I took an old ego spinner that failed when I dropped it, and popped off the center pin and jacked the washer. I replaced the vamo washer with that one, and I am back in the game. No additional problems to report.
I use the vision 1.6ml clearomizer, vivi nova's, RSST, smoktech dct, and my favorites the Vapeonly BCC. Can't go wrong. I like the size and feel in my hand using the 18350's when out and about and the 650's when at home. The vamo costs slightly more than a 1300mah ego spinner, which is why I got one. Well I was ...... that I dropped the spinner, and the fire button stuck, and that was all she wrote.
What should you get? Whatever keeps you from buying an overpriced pack of cancer stinkys.
