I have one. Its a very good vaporizer for the money. The only things I don't like about it are that its kind of inconvenient to have to hold the vaporizer and change the bag at the same time. You cant set it down because of the way the fan is set up. Also, every 2 ounces or so of use, you have to soak the pull out drawer and the herb disks in isopropyl, otherwise they get so sticky that you cant change a disk easily. Other than that, I think it works great. Best vaporizer I've used for the price. Had mine for a while now, and its definitely paid for it self.
