I just finished reading this entire thread. Great info. FC turned me onto the Cloud and its still my fave. I am an occasional recreational user and the Cloud and Firefly work great for me. My wife is a frequent medical user. She has MS and a few other medical conditions. She had part of her lung removed and has emphysema. She has problems drawing hard enough to get good hits from the Cloud so she has gone back to the bong. Herbie seems like my path to get her to vaporize. It appears that with fan assist that Herbie will power a HT so that she can hit it like a regular bong. Right? All sales are final so I don't want to spend big bucks on something that she can't hit like the bong she is used to. Thanks for any responses.
