I recently just bought a 50$ vaporizer, it works great but the expensive ones are where it gets great. The 50$ one is a hassle and gets really hot at the glass bulb and you have to watch out not to burn yourself etc, also the high you get varies on your temperature. But when you buy like a 300$ + vaporizer, you get one that's legit, and fills up like a bag with smoke. You then inhale this smoke whenever u want as the bag is sealed and only lets smoke in through 1 way. Its much better than the normal crappy vaporizer and i do hope you invest in it, it is definitively worth it.
