The Chameleon Glass pipes look very intriguing, I reached out to the excellent RVS customer service asking how they would compare to the gold standard of hash vaporisation, which clearly is the Vapman, and if they have a favorite between the two. Here’s what Matt came back with, his reply might help all the hash connoisseurs following this thread.
‘Thanks for your email. These are quite different from the vapman as they are completely manual and conduction based so provide a slightly different vapor profile and more fine control over the amount of vapor you inhale, being that you can apply the heater directly to the material as required. When the hot stick is heated correctly they provide very accurate flavour and a nicely customisable experience, without the need to inhale the contents in one fell swoop which is how most people seem to use the vapman. They also have quite a bit more capacity so can be loaded up with more, then vaporized as desired by re-heating and applying the hot stick to the contents. They can also be used as a single hit extractor by continually applying the hot stick to the contents, after it's been heated, and inhaling continuously. With a little practice they are highly effective but it's difficult to directly compare the two as their function and input is so different! Both do an excellent job when used correctly.
Personally I prefer the Gandalf, they both function exactly the same in terms of user input, but the gandalf has a longer stem which provides more cooling of the vapor. Some people prefer the hotter vapor especially when transferring over from smoking, however I suspect if you are using the vapman already and are used to vaporization through glassware, the Gandalf may be more up your street.’
