I'll give some initial impressions. Only had it one day so far.
Its a completely different beast to the v1.
Feels good in the hand, well made.
Some kinda case is essential, otherwise you have no where to stick a hot piece of metal. I brought a pen case, thought I was getting the leather one I usually use for other TEDS. Turns out to be a cheaper one that melted. Bummer. Another is on its way. Kinda a shame it did not come with one, seeing its pretty much an essential item.
I like that you can select an airport setting and kinda lock it in place. Nice touch.
It hits way harder than the v1. Bigger bowl, bigger hits and finishes the bowl quicker. I think for most people that's a positive.
However it also is a trade off. Its hotter than the v1 (I generally max the cooling on the v1) and it makes my cough more. Will it be to harsh for my old lungs? Not sure.
So do I prefer the v1 or v2? Its too early to say for me. At the moment my v1 is edging it. Just because the vapour is more comfortable.
The v2 does look like it would be awesome through water. Must try it.
