Never tried a HotBox, but I love my Hands-free VB! You use less pot with the same level of high, it's easy on the lungs, doesn't smell like pot and actually has very little odor! One thing I really like is that if I'm posting, I can take a hit, type for 10 minutes and then take the next hit! No wasted THC! I'm very happy with mine! - Granny:hippy:
