I got the SE and I already have the Air Max. I can say that they both perform very similar. I'd go into further detail, but it wouldn't be far off from what you can read on the Air Max. The main difference I can say is that the SE body is all plastic and the Max feels metal. Also, the SE utilizes a 18650 battery, which is much more common and affordable and the information screen on the SE is very limited and can be a little confusing compared to the Max.
Like the Air Max, it is definitely a sipper and I believe comes at an amazing price point for what you get. I would very much recommend this as the first "starter" vape for anyone interested in getting into the hobby. I might go as far and say that it is the best vape you can get at that price point. The only vape I would recommend at the similar price is the Starry4.
I own POTV One and V3 pro and I would reach for the SE over these two ANY day. V3 I find has too much draw resistance for my liking and the POTV One has always had this plasticky taste that I never got to go away, although I haven't heard other people complain about that issue with their POTV, could be just my unit. Packing, cleaning and maintaining the SE is also an all around better experience with the SE. Pretty much just have to worry about packing and cleaning the stem of the unit.
I will say though, just like the Air Max, this unit works best when you let the vape reach temperature and then let it heat soak for another minute or two. Most new comers aren't aware of the benefits of letting their unit heat soak and will most likely feel disappointed the first time they use their unit, as I was. It was through reading tips and trial and error that I discovered how to let the Arizer vapes shine.
