It's been used heavily and dropped several times, but it still works fine! When I was looking for a vaporizer, I checked the (then) available types and the VB came out as the best for me. No bags to buy, quiet, low odor, small, nothing to break down, easy to use, your next hit waits for you with no lost THC and the "leftovers" from vaping make decent brownies..... What's not to love?
