I had 2 vapor brothers before getting the herbalaire. I sold the first one and still have a hands free vapor brothers. Comparing direct hits from the herbalaire with hits from the vapor brothers I like the vapor brothers better. I can take bigger hits from the vapor brothers and i like taking 20 second hits.(that might be because the herbalaire gives me more concentrated hits, i don't know).

Without a doubt the herbalaire is more efficient though. I save the spent stuff from the vapor brothers and make some pretty superb brownies, so i know i'm not getting everything with the vapor brothers.

With the herbalaire though, the stuff comes out looking like death. no joke.
