I use my herbalAire every day and have been for almost 2 yrs. I don't use it much for direct draw but it heats up in a couple of minutes and you can get some quick hits that way. For bag use it's great. I don't like the thicker bags they're supplying with it now. They won't burst if you overfill, but if you get distracted and forget you're filling a bag the vapor will leak out (like a safety valve). I use Toppits oven bags (Reynolds are cheap too) and make different size bags. It's easier and cheaper to make multiple bags than the Volcano, easier to clean, and just as efficient at extracting THC. It does fill slower than the Volcano, but making smaller bags and switching them off compensates. It's got a separate pump so there's more 'stuff' to deal with, but it's not a big deal to me. The pump is pretty quiet and if it should fail just buy an aquarium pump.
