In my opinion it is better than every gan cube ever made in a lot of ways.
First off gan cubes are only better in any way because gan cubes are light
Second it has very helpful ridges that help tremendously with grip
Third it is the fastest cube I’ve ever turned by far
Fourth it is fairly stable like not as stable as a qiyi cube or something but I can still turn it comfortably without any problems at all
Last it is a good size and preety cheap for its price because if I made it I would sell it for $10 more than gan cubes judging by the quality of it

This cube is great after setting up. OOTB this cube is very uncontrollable and fast. However, after tensioning and lubing with some weight 5, this cube is my new main. Overall, this cube is great after setting up.

I had a GTS3M a couple years ago and gave it away to a friend who was getting into cubing. Have used other cubes since then, but have ordered another GTS3M. It has a great adjustment system, feels right in the hands, turns are quick and precise and magnets seems to be just the right strength. For me it is fun to use the cube, although each individual has their own style. I ordered it with the lube service and it was great out of the box.

This took over my main. My old main was the gan xs but this needed setup after setup this was an instant main. Don’t hesitate from buying this I definitely recommend this.

I have wanted this cube since 2018 but I didn't get it. But I do have to say the ridges are amazing. A lot of people don't like them but they actually do help with grip. Younreally don't notice them either. The cube is also really smooth and fast! There is quite a bit of spring noise but still it is an amazing cube!

So sooooooooooo good Its my first speed cube and and its so good that I can not discribe it in words

I like this cube, the feel is nice and it’s got good speed ootb, but it’s kinda clacky/ loudish, a bit snappy on corner cutting, flexible, and even though people say the magnets are on the stronger side, I could personally stand for them to be just slightly stronger, but that’s probably just me being inaccurate. In any case, for a 2+ year old cube, it’s still decent even compared to more recent flagships.

This cube is perfect for me EXCEPT that I wish it had even stronger magnets. I know lots of people prefer lighter magnets (hence the LM version), but I guess I’m unusual in that I prefer really strong magnets. I may also be unusual in that I really like the ridges.

Exceeded my expectations exponentially. The two biggest things that would have kept me from buying it is the ridges, and its weight. When I got it felt noisy, but considering that my old main was the Dayan tengyun is understandable. It also felt and feels incredibly stable, and incredibly speedy. The ridges help me with my cube rotations, and my hands are small, the weight made it feel more solid in many hands, and lastly the magnets made the pieces align so I could just transfer to the next turn immediately. Those 3 factors made it very stable, and allow the speed to be controlled, optimizing my turn speed. GREAT CUBE

This cube has strong magnets, pvc coating, easy to remove center caps, and a cool spring adjustment system which allows you to make the cube feel tighter than it really is which might have been the reason it became my main. The gts3m became my main over the gam 11 m pro. The gts3m is just my preference over the gan 11 m pro. The cube is fast, loose and magnets are strong out of the box. Overall this cube is definitely main worthy for anyone.
