There's many different types and styles of vaporizers. Which ones do you use? Ones for flower or oil? I bought this one for Mrs tangent over a year ago to vape her medicine, and she didn't use it until just recently. Why? She said she just like smoking a little bowl load. She thought she'd give it a try now. It's made by Grenco Science out of California and is pretty cool. Small and handy. Heats up pretty quick. It has 3 temperature settings. Shuts off after 4 minutes. She's really liking it. She said it seems a bit odd that nothing comes out while exhaling, but the effects for her are the same as burning bud. In other words - it works.. The chamber holds less ground up flower than the glass pipe she has been using, so there's some added homegrown savings. Even the graphics are cool... What vaporizer are you using or have used? Any personal reviews? Let's see 'em!
