http://thermovape.com/collections/all/products/alpha-ultralite (direct link to product) I just got one of these, and wanted to share a bit of my experience with it. It is the smallest of the Thermovape vaporizer products. I am using mine with the Dart LV (as shown in the stock photo) Mine is still new, just got it, so I plan to test it out, see how well it performs w/ the Dart using the 10440 IMR batteries that came with it. First impressions, dang! this thing it tiny!! I charged up my batteries, attached the Rev/Dart which had recently been loaded and was ready to roll, noticed it takes about a 10 second heat up from a cold start. I did a series of 8 second hits, waiting about a minute between them, giving it another 5 sec warm up, got to hit number 5 and the Ultralite body started to heat up, so I put it down to give it a rest. I will keep testing the battery life and add more info about that later... In the mean time, here are a couple of photos of my Ultralite next to the Evolution and the T1, for size comparison.
