The Crafty: An unreliable, over-rated, over-priced, gimmick-laden, piece of plastic. Its sole merits: a quickly-concealed swivelling mouthpiece and easy draw. This lopsided, dust-and-dirt collecting unit ignores basic design principles, and would have raised laughs and eyebrows among the first year industrial design students I lectured in 1990s. The outsized flashing charging/heating lights, and noisy vibrating feature, major distractions, and only two temperature settings, unless you use a cell phone. Another gimmick. Plus four replaceable (bright blue) sealing rings. I can hardly believe the Crafty has received so many accolades. A rip-off @ around AUD$400. For the same price or less, get yourself a superbly designed, solid metal alloy body Arizer Air (AUD$242 with discount), PLUS the elegant, much-improved Flowermate Vapormax PRO, a bargain @ AUD$155 introduced around New Year 2015-16, with many innovative features. Either one is superior to the Crafty. For intending Crafty buyers, buying the Air and Flowermate together should be a no-brainer.
