Too bad, you don't want a bottom feeder, I would have suggested a Reos mods.
reosmods.com
I predict It would have been the last personnal vaporizer you bought. Check out their forum:
Reos Mods They are very friendly and helpful.
Most reonauts have been through just about every personnal vaporizers that's on the market before they arrived at Reoville. Most have just either sold their old vaporizers or it is gathering dust. Reos are bottom feeders, it is like dripping when it comes to flavor and vapor production but without the problems of dripping.
The owner, Robert offers outstanding personnal support to everyone of his customers. Reos don't die, as a matter of fact there is nothing that can break on a Reo that can not be easily replaced for a few dollars. I have yet to see any negative posts on ecf about Reos.
Save your money, don't buy the new model every 6 months or so as they become obsolete. Buy a Reo, it will be your final vaporizer.
