Vamo version 4 is out in Great Britian, which is the V2 tube with the V3 chip and top. If you like the V2 style wait for the V4 to become available in the USA, or if you like the swirls on the V3 go for it. The Vamo V2, V3 or V4 is the most cost effective way to get into VV/VW. Build quality is pretty good. I have had my Stainless Steel Model since October 2012. It is used all day every day and works like it did on day one. I suggest getting the Stainless model and the $2.99 air controller for the top from madvapes.com which will protect your top threads, the inner O ring, and provide air control for
tanks. Of course the ProVari is a better built
device but three times more expensive.
