I have all three, Fury 2, Mighty and Square.
Each are very strong units and if you don't have a lot to compare to, would probably make you very happy.
Each have their perks, the Mighty may still be the best all around, but it is full session IMO. Was the first I reached for before I got a F2.
The F2 is now my go to portable. It's the fastest heat up time, gives great results, battery works fine for me for a normal day..... It's very impressive before you take it's size into consideration, but it's also a session vape that can be coaxed into close to on demand.
The Square is truly on demand which alone sets it apart from the other two. The battery must hold out fine because I think I've only checked it once or twice since I've had it (at the beginning). The vapor is very cool, even at higher temps. The four chambers is either great or a PITA depending on how you're using it, it can be a messy vape. I'm picking up small things about it as I use it more, most of them good. I did a deep cleaning on it this morning and realized as I pulled silicone apart that one of the filters had a lot of duff where it shouldn't have been. Last time I put it together I must not have seated it properly, I wonder how it affected performance.
The one thing that does get to me about this one is the mouthpiece. It could be a touch longer, very minor gripe. It cools the vapor very well, love it for that! I consider the fit a fail. The other day, with the unit cold, I ended up turning it upside down as I looked at the chamber dots, and it fell out. Nothing attached, not moving fast, just fell out. It's also loose during use, I never feel like it's secure.
All in all, I really like the Square and have enjoyed getting to know it. I think there's more to learn, but I'm already satisfied. It does everything well and has a battery to back it up the way I use it.
Typical session - ~.15g in one "session" starting at 380F taking from 5 sec to full timeout draws at a moderate speed for about 6-8 pulls and then finishing off at 415F with the same draws above until it's done. No stirring, even ABV, I think it's a very strong extractor.
**Edit - I keep seeing 450F as the highest temp. I have a Pro and have gone into the settings multiple times, and the highest I can get the sliders to go is 430F, am I missing something?
