Very nice digital vaporizer but it just doesn’t work. Very light taste, a battery last 20 minutes which is about a quarter of the time it takes to warm up. When the Vapir Vaporizer warms up, the taste is light. The Vapir Vaporizer instructions say it takes 20 minutes per bowl of marijuana. Imagine a light taste for 20 minutes and a dry throat. Bad vaporizer, one of the worst vaporizers we have ever seen. Plastic also. This marijuana vaporizer is from air-2.com.
