PuffItUp offered the best price, free shipping and a decent free grinder so the experience with them was super. The Slick has proven to be a good quality unit delivering powerful hits and a good battery life. I like that it works well with the small dosing cannister on the highest temp setting and on the medium heat setting for loose material in the chamber. I also have a Flowermate V5.OS which, while being a high quality unit, does not work well with the dosing capsule even when on the highest heat setting. I frankly prefer the less expensive Slick to the V5 in several ways but the V5 does carry better in the pocket for outdoor use. Anyway, the Slick produces great clouds when loosely packed and on medium heat. The chamber holds sufficient product for a couple of sharing users while the capsule is best for a solo sesh. The vibration feature is a nice touch, letting you know when temp is reached and also when it times out. The replaceable lithium battery is another big plus. I expect this vape to service me for a couple of years at least. The build quality is impressive. I'd say if you're on a limited budget, you can't go wrong.
