Trog had a better experience than I did. Mine never produced much vapor -- and dripping drowned it to uselessness. It was also awkward to use and carry. You can't clench the heavy thing in your teeth and you can break a tooth easily if you bang the pipe into it. Just not a good design. And who wants to look like Sherlock Holmes?
But, as Trog said, big cart, long battery life. Just lousy design -- not to mention the atomizer can't be individually changed. You must
throw away the whole body of the pipe! What a waste. Nice idea. Dumb execution.
