You will not go wrong with the V tower exteme vaporizer. I got mine last week and used the shit out of it all weekend long. There is seriously no wasted vapor in this thing. I like how you can take whip hits with it without using the fan and that you can just fill up the bags with the vapor. The only thing I think you would ever have to replace over time is the bags but other than that, everything else ca be cleaned. I say go for it while they are cheap. No bad reviews from me at all on this thing. I have a Vapir 5.0 and this thing puts it to shame no doubt. Happy Vaping!!! :thumbsup:
