The VV ego is the Lavatube from what I understand. Made by the same company. I believe they are coming out with a new one, also, called the "twist". I just can't recommend a VV like the Lavatube that limits what you can vape on it.
If you are in the market for a budget VV, I would look at either the EVO at sweet-vapes or one of Ken's box VV's at Ken's box mods. Both have gotten very good reviews and do not have the limitations of the Lavatube.
