I have a very small review that I feel on HerbalAire â?¦.

Both Volcano and HerbarlAire are very efficient. The Volcano will fill the same size bag quicker, but that's not a big deal The HerbalAire doesnâ??t have a valve on the bag, but once you've taken a hit or two you can set the bag down without losing much vapor at all, and making and using multiple bags is easier and cheaper. Volcano warranty is longer and they're probably the most stable Vape Company of all. HerbalAire has great customer service. HerbalAire has a separate pump, so you've got more cords and stuff to deal with, but if the pump fails down the road, just substitute an inexpensive aquarium pump and you're back in business. The HerbalAire can also do direct draw, so that's a bonus. It heats up fast so if you want to crank it up and get a quick hit, it's hard to beat. It also has auto shut-off, so if you forget to turn it off-no problem...:rasta:
