This is a really nice dry herb vaporizer! (Depending on the quality of the material you put in it) it provides a good flavour and is smooth on the draw (although the Volcano unit provides a much cooler inhilation experience). Very effective in delivering a medicated dose. Not hard to toke through like some cheaper vaporizers although there is some resistance. The dosing capsules (sold separately) make refilling the oven easy and inconspicuous on the go. The herb comes out a good dark brown colour after a session, especially if you use the two 15°C boost functions. The cooling unit is quick to dismantle for cleaning with Isopropyl Alcohol. Tackile in the hand and discrete for use out and about. When it heats up the bodys radiator design helps keep the outside of the vaporizer cool to the touch. The battery lasts around three sessions then needs to be recharged - recharging takes about one and a half hours. The extended warranty is good for peace of mind too what with the unit being quite pricy.Iv had the device for over a year and a half now and iv had no issues.
