The concentrate adapter seems to get mixed reviews. Easily scratches? The Pax 2 is cheaper- but really not by much. If I spend $200 or $275, it doesn't make much of a difference to me.
It's not much of a price difference at all, and if you add a half pack lid for the Pax 2 there's even less difference. The Pax 3 already comes with a half pack lid.
I didn't really need the concentrate insert but the other benefits are attractive too and might work for you out at festivals and things.
As the battery run time is further improved in Pax 3, also the heat up time is really fast. And I think vibration when ready is new too.
The raised MP runs cooler than before and you can set a custom temp in the app I believe.
Plus it has advanced lip/motion sensing combined with temperature control to cook the load less between draws and extend flavor.
If you don't like the insert you could sell that and it's certain a Pax 2 owner will buy it!
Or if you're sure your pen is enough just sell the insert unused.
You might find some uses for it, I find it works good in my light, limited use in that department, comparable to a Volcano with liquid pad for me, except portable!
I got a black Pax 3 and I keep it in a pouch when not in use and the finish is holding up fine.
I did wonder if it's possible the shiny finish could transfer warmth to your lips easier than the matte of the Pax 2 but it's not actually a problem and I like the look and feel of my Pax 3 in black, even though part of me wanted a gold one too!
If you're lucky you might find somewhere that will give 10% off!
I'm sure the Pax 2 would also impress but you could be thankful of the upgrades of the 3 quite often, or when you need them most. It really is a device you can charge up, take somewhere and not be worried about a charger or batteries for a good while.
I've jotted down a lot of thoughts about my Pax 3 and I really like the unit, just have to get round to condensing it and posting it up here as a sort of review.
It gives me a new appreciation for the people who do reviews and the efforts involved to give all those opinions that make sense!
