This puzzle is pure joy to solve! An amazing setup on an amazing cube!
Great cube and setup. Highly recommend
Angstrom AoSu 4x4 GTS2 M
This cube is great. The outers are like turning a cloud and the magnet strength is great. The inners though, have very strong magnets, a bit too strong for my liking. you don't really feel them while solving though, which is what is important. the Angstrom setup is amazing and 9.9/10 would always reccomend this cube.
I really like the feeling and speed of this cube. Out of the box it was super sluggish and slow, but after 50 break in solves this cube felt very stable, somewhat blocky, and fast and smooth.
This cube does turn amazingly well, I recommend this cube over the valk and any non-angstrom setup. In the first two weeks it turned exactly like a 3x3 which was amazing, but now it feels more ordinary. It is still extremely nice though, I just wish they had put more lube in it. As many have said already, my times dropped significantly with this puzzle, I am finally under a minute! In terms of feel comparison for 4x4, the valk 4 feels like the valk m 3x3, and the aosu gts2m feels like the gts 2m 3x3, if anyone was wondering.
Ever since I got this a few months ago, I have broken all my PB’s over and over again. A huge upgrade over my previous main. Definitely would recommend to anybody that is very serious when it comes to 4x4
The angstrom lube mixes PERFECTLY with this cube! It's got better performance than most 3x3s after you break it in a little (lube is a bit thick out of the box.) I went from a home magnetized Wuque, great cube! To this and I'll never go back. When you see reviewers saying it's very stable that's true but you probably assume that means bad corner cutting or slightly harder turning but that's just not the case. It has this insanely smooth almost glossy turning probably thanks to the angstrom lubes and no lock ups or pops. This cube is so good that I went from thinking 4x4 was cool to it now being my main event. I just wish I knew exactly how they lubed it so I could freshen it up but it still feels well lubed after 200-300 solves.
When I opened it it was already very good, the outer layers were fantastic but the inner layers needed some work. After doing about 50 solves the cube was broken in much more and i fell in love with this cube. I broke all my PBs and now my PB single is 38.26 and im looking to improve it furder in the future. I recomend this cube to anyone looking to improve in 4x4 if you already dont have a great cube to solve with
