The cube comes out with a very tactile fast feel but that's because of the square centers. After tinkering with the tensions and centers, it got really fast but not crazy and I could get much crazier tps. Very good cube but u need to put some dignitas or silk to get rid of the tiny catches.
PS: The center caps are super hard to remove.

The only complaint I have is the center caps. It’s super annoying that you have to use the tool in order to take them off.

Matty Hiroto Inaba made me get it

This cube is not worth it’s money it’s good but it’s lockeds up way to much you have to turn very light for it to preform at top level and it’s still has this weird feeling with it be so light it’s just hard to control I believe the 14 and 12 are still better then this cube don’t waste your money gan is starting to become the iPhone or cubing and I will stop buying there cubes if I don’t see improvement in the next one.

Feels very light, making it ideal for long sessions, or just cubing throughout the day. My moyu was quite heavy so my hands got tired after a few hours, but k don’t notice that with the Gan. It also has very good stability and control, but does take some time to get used to if you have never used something like the Gan 12.

Wow. This cube is super fast and light out of the box. I used Lubicle 1 on it because it seems to harden and protect without affecting speed. For me, it feels faster than my favorite cube the Gan 12 but with better tech. I’m very impressed.

I came from the Gan 11 M Pro, being able to adjust how hard it is to turn, and the changes being drastic. Switching from the 11 to the 15 made me think the cube was broken. Setting 6 still feels very very loose, and the cube doesn’t even feel like it has magnets. If you are looking for a rough cube, buy a tornado or anything else. I’m not going to let 70 dollars go to waste so I guess i just have to adjust to it. In my opinion it is just really loose, but i can see why people like it, and plus i don’t know if they have made the 12,13, and 14 like the way they made the 15 because i haven’t tried any other cubes. Still a decent cube tho, just not what i expected.

I is cool my first gan btw

Takes a little setup, but I think that it is better than the 12 in a few ways, but not a huge step up. I think that people that like fast flexible cubes will like this, with the 12 being just a little slower and more blocky. Good cube, and I have gotten many good solves on it so far.

I loved the GAN 11M Pro. It’s been my main cube for years. I got the 12 and it wasn’t as stable as the 11. The 15 is the perfect balance between the two. I’ve set it on the tighter side and it has great stability like the 11 but is faster and lighter. It locks up a little from time to time but I’m not even close to a fast turner so it’s not an issue for me. Great cube for those that like GAN and want something more like the 11.
