First vape I've owned, though I've used the volcano. Paid $140, but would still be plenty happy with a price nearly $100 more. We all know the basics, so let's go over my personal method of operation...
The whip just didn't do much for me. The bag is where it's at. I warm the herbs at 100C for ten minutes or so, maybe longer, bag attached and everything. Then I crank it to 200 or 210 and hit fan speed three. This will get you a bag or two, and will be fine for most people's uses. If you're looking to stretch your semi-used herb, increase the temp while LOWERING the fan speed and get that last bag or two out. I can get a very effective bag at 230C, fan speed 1. FYI I did try a low fan speed on a new batch, and it blew me away to the point of almost not being able to speak. It was too strong, and believe me, I've been known to put down some herbs. Better to pace it. If the vapor is too hot at these levels (I don't mind it, GF does) put an ice cube in your mouth when you draw in.
The health benefits are amazing. I was smoking 2-4 bowls a day, and I began developing shortness of breath on stairs, sinus infections, stuffy nose, headaches, dry throat, dry eyes, etc... just like a someone who smokes a pack of cigs a day. Since switching to the vape almost exclusively, that has all cleared up. If you're allergic to smoke like me, get one yesterday and you'll thank yourself forever. Test it yourself, take a device hit and blow into a paper towel. Look at all the gunk. Now do the same with a vape hit... nothing at all. The proof is in the pudding. This is the fastest, safest way to get high (edibles excluded due to the slow acting nature).
The cons: my GF took it out of the package and immediately broke a glass part. Luckily it came with two. Do yourself a favor and buy spares, and keep them separate. Nothing is worse than someone party fouling hard and ruining your vape session. The unit is expensive, kinda, but really you'd spend about the same on a few nice devices, so stfu and start a change jar, eat some ramen for dinner, and buy one. While the unit has an auto shut off (great for when you fall asleep), then fan will go and go until you tell it to stop. Letting it run will ruin the bag and waste your herb. Pay attention!! The parts get gunky with resin after heavy usage. They aren't too hard to clean, just be careful and don't mess up the screens. Also, you will ingest more potent air than you ever thought you could because of the ease... this could be a pro or a con ;)
BONUS: my unit came with an offer for an $8 metal grinder. Um, YES! The more surface area, the better this thing will work! Get a grinder!
OVERALL: If you smoke herb more than once every couple weeks, you need one of these. You need it like the desert needs the rain and a fat kid needs cake. You need it all week and twice on sunday. GET ONE. NOW.
