I tried many but for comfort looks portability durability and a quality fully controllable hit (with a little practice) that the Alivi8 is great
http://alivi8.com/ It has really grown on me due to its dependability made of medical steel and requires no battery only a lighter and the vape is so good that several vapers who tried mine decided to order one and switch - I am a newbie here but have a fair bit of vaping experience and find this the perfect toke whilst driving or hiking in yonder MJ mountains, I do not make recommendations often but I swear this sucker has given the best most reliable power medication from any smoking device and I have tried thousands so it is worth adding to the collection if u can afford it, for me it was pricey but the hit was so unique I had to get it, the only downsides that I can find are that it is heavy although small and the head stays hot for a few minutes so you would need to wait a mo before putting it in back in your jeans pocket
important note - I have the steel version which is 120 grammes and cools the smoke right down instantly but the 40 gramme anodized version they sell is lighter but for me is not the same and the thing needs to be at least tried and played with as the website fails to show the beauty of the engineering in their pics and it is fascinating to open it and see how smart they were in creating this gem of a vaper also good for clumsy oafs like me as it is almost unbreakable

It also feels like back to basics after trying all the gadgets :smoke:A vape that feels like a joint in my gob but delivers a safe simple medical dose
