I have a Vapor Brother's. Yes, they work! There is very little smell and you use a bit less. The high is slightly different, since you aren't getting combustion bi-products. It's a bit more "heady", less "sleepy". The "duff", the leftover pot, is still able to give you a bit of a buzz when you use it in brownies. I have the hands-free type and it is easy to use. Changing the screens is a bit tricky (get the small size screens).

I've toked for 40 years and my lungs were a mess. It took just two weeks of just vaping for them to be totally clear! No more morning cough! Get a vaporizer! Mine ran me less than $140 and was worth every penny! -Granny:hippy:
