Been following, and carefully investing in vapourisers for a couple of years now, and finally invested in my first convection type vapouriser. The INAVAP conduction (plate type), waste of time, last about a week with heavy use.
I havnt tried other convection type vapourisers - so i cant rate the inavap to them, except the cheap vapouriser , the test tube thing, worked well with a torch lighter!
The INAVAP, take a little while to get used to optimum ways of taking hits. Which on the first day after 2 hours continuous use, found my lung quite hot and sore. You soon learn to take softer, controlled hits and you then dont really notice the heat.
The InAvap is very efficient with whatever aromatherapy oil or ethnotonical plant you use.
One final note, you can get so much higher with a good vapouriser, compared to smoking - i think experienced vapour gurus will agree, the INAVAP delivers !! i should work for them!
Im in the UK, and you need a UK transformer to use it, but it works well with it, ive seen them on ebay UK now!
