Just a bit of a follow-up:
I love the Air Max and use it every day. I doubt I will ever find a better road device. It is great at bedside or on the deck. It heats up fast and hits hard. I love cranking it up to about 214C and hitting it through water.
My main go-to these days though is the dynavaps. Holeee foook do these things hit hard. I've had and used and enjoyed my dynavaps for years but two developments have made it my main cannabis consumption device. First is the FMJ. Not having to spin the device is huge. You can heat it up right on the bong and even by hand it is just easier.
Second is that I've started buying my torches from hardware stores. Torches as opposed to lighters are far superior. They are more robust and durable, they are cheaper, and most important, far less finicky. They don't need to be purged of air when refilling like most of the lighters do. I've got 3 torches and 4 or 5 lighters and the lighters are all in a drawer now.
This was $15 and works great:
This was about $20 and also a great device.
