I just purchased the v tower extreme vaporizer last night and it had lots of supporters out there and its kinda like a mini volcano. You can use a whip or bags with it. Its a vapor on demand type vaporizer. I have a vapir 5.0 also but I wanted something more quality and better vape. I will let you know how this one goes when I get it in. I did alot of reading on it and I almost went with a volcano until I saw this one. Its actually on sale for 299.99 but I did find it for even cheaper at Herbalaire, Extreme, V-Tower, Volcano, VaporGenie for 279.99 and that was the final price. No taxes or shipping costs.
