I felt one at sac cubing comp when I felt it was slightly crunchy then its speed went .............................ogga boooooga oggaaaa boooggggga omaiwa moshdieu ...N-Nani? Ooooga booooooga ooooga bbooooogga IMPOSSIBLE SPEEDDAAAAA A-hhhem it was also very smooth great

Not a lot of adjustment needed out if the box. Combines the soft feel of the Yusu (with less risk of popping or misalignment) with the magnetic stability of newer cubes. Also feels a tad smaller than say, the Qiyi Magnetic. All these combine for a plush turning experience that lets you play for longer times and delay hand-fatigue. My family also points out that is one of the quieter 4x4's I have purchased, so I am allowed (LoL) to watch TV in the living room while solving.

I have the GTS2M which has VERY strong magnets on the inner
layers, so I decided to give this previous GTS a try. Real glad I did XD
OOTB this cube performs wonderfully, fast yet controllable with
nice moderate magnet strength on the inner layers and slightly
weaker on the outers for a superb 3x3 experience.

This cube is pretty okay. It doesn't do much reverse corner cutting, but can do almost 45 degrees normal cutting with a decent setup. I do feel like it needs stronger magnets though. Here's the thing though - this is the same exact cube as the RS4M pretty much, just with no screwdriver and glossy plastic on the outside. And it's cheaper. So if you want a good 4x4 for cheap, the RS4M isn't the way to go - it's this cube.

I only had two other 4x4's and they both suck, this cube was a breath of fresh air. I was finally able to push TPS on bigger cubes.

Nice crunchy turning, the only qualm I have is that there are occasional pops/lockups of the internal pieces which are very hard to fix and can last 10 seconds on a bad day, although these only happen to me maybe once in 25 solves. Excellent turning!

I got it on sale and wanted to give magnetized 4x4 a try. I have to say it's a good cube for those of us who are casual cubers and not serious into speed.

The magnets seem a little weak to me. I could do with just a little more. I have two magnetic 3x3 cubes with different strengths I used as comparison. The centers are stronger than the outer layers, however, which helps with the 3x3 stage.

The center pieces are solid so there's no worry about caps falling off (a huge problem I have with the ShengShou Tank).

If it's available for sale and you're curious about 4x4 magnetic, I don't think you could go wrong by buying this cube.

Got this on sale. It was an amazing purchase for the 11 dollars I paid, but I'm not as sure how worth it it would be at 30. In any case, you get a very solid magnetized 4x4. Hard to go wrong.

For $12 at the moment of 10/2/2020 this is amazing 4x4, with great corner cutting, speed ,and not overly strong magnets this is a AMAZING cube.

Upgraded to this from a non-speed cube. What a huge difference! I no longer feel like I’m fighting with the cube as I solve it.
