The Gans 356 air Ultimate is my new main. Straight out of the box it has smooth and silky turning style. The cube is very light and I use the yellow GES nuts in my set up, it doesn't flex really far and is still very quick. The magnets are not that noticeable in less your turning it very slow. So in conclusion i have to say that this cube is a buy.

I baught two. The cube ships with a "certificate" in credit card format (unfortunately I don't know which card belongs to which of my 2 cubes).
It is clearly lighter than the "Gans 365 Air Master". But for my Lever (about 35" to 45") it does not make any difference. The "turning" is a bit louder than the "Gans 365 Air Master", so when I train while travelling in the train, I prefer the "Gans 365 Air Master" not to desturb the other passengers.
Like ever, I stick my cubes myself.

I had to test each set of screws to see which was my best. I enjoyed the feel of the greens, but I got the best times with the yellows. It catches a little. And that's not just the screws I have in. I noticed it corner cut about the same no matter which screws you used. I enjoyed that portion. I do enjoy the feel of my GTS 2 more though. Still better than the Guo Guan to me, original not pro. I haven't tried the pro yet. Also, good luck on having the corners twist. It is quite light. Update: I went over to the blues and now I'm starting to get better times with those, but the looser the screw set the easier the corners twist. It has become my new main.

Overall this puzzle is great.The only downside is how dry it is.But once you put any lube in it it's fine.

I bought this cube one week before the GAN air sm came out and at a comp after that I got to try a few sm’s and they are sooooooo much better!
This cube is amazing! And it dropped my best time by 5-6 seconds and I like it a lot and it is my main but definitely spend the extra and get the sm.
I am giving this a 5 star review because it definitely deserves it.
I use the clear GES nuts and use GAN lube.
It’s sometimes very hard to use lighter tensions though and would work a lot better with magnets.

Way better than my previous main, valk3. It's very fast and smooth. I use purple nuts and put silk on the pieces.

My cube was absolutely amazing and I was using the stock green GES.... The 3rd week of having this thing it exploded in a big mass of prices while doing an untimed solve! The cube just exploded and I almost had the prices fly out my window. Not very good quality got the expense

It's a great cube but I was a little upset that the pieces are all glued together and you can not add your own magnets. Unlike the plane normal air that had screws where you can take apart each piece. ... my advice, save the $10 or $15 bucks and get the plane Air and not the ultimate so you can mod it and add magnets if you want.

Este cubo lo compro mi hermano es bastante rapido y bueno. Fuera de la caja era rapido y estable y el corte de esquina era muy bueno a mi me gustan los springs blancos y los springs amarillos, pero siento que el precio es demasiado caro
