I have just received this product through a custom ordering process, and this cube is unfortunately not good at all. The cube suffers from many weird properties, such as an extremely audible *click* when reverse corner cutting, which is extremely annoying during solves. There is also a weird piece separation property, where the edges seem really loose between the two centers. The cube doesn't want to flow, and i've tried 4 different turning styles, in which none of them worked. This cube is the first cube that I've come across that is utterly unusable. However, i do not blame this on the Pro Shop (per say). They did the lubing well and they worked with what they had. (They also used green instead of yellow nuts like usual, but thats ok considering i forgot to specify) Rather. I blame this completely on the SM 2019. As the batches go on, I've noticed that they have gotten worse and worse unfortunately. But on fault of the Pro Shop, I felt like during the quality assurance stage, they would have recognized that this is not a very good product, and that it just wasn't good. But thats up to Rowe (Rowe did the quality assurance).

I regret spending 83 dollars on a less than mediocre cube. (BTW, i really do appreciate the discount however!)

I got this cube for my birthday and i was so happy and a right away made it my main it is really smooth and the magnetic bump felt so nice! Definitely recommend it!

These Gan cubes are really good out of the box.

Out of the box, it is way to slow. I tried to break it in but it just wouldn't. After about 500 solves and a few drops of Compound V. This cube became insanely good. It was stable enough for fast algs and Fast enough for LSE (I use Roux). It's a bit pricey but it's a better value over the GAN 356 X in my opinion. If you do get this cube. Do pick up plently of Silk or Compound V as they increase the performance a lot. In terms of feel, it's nowhere as smooth as the X but it has that signature magnetic bump.

Instantly got a pb after 9 solves. The cube is beyon My expectations. I got a original some month before and I hate it after some solves. I hate the plasticy feel of it an theres no buttery smooth feelongs that others discribed. But the angstrom verison is a mricale it got rid of the plasticy feel and added more of a feelin on a gan 356 x which is My main. This cube has became My back up main on th day I recieved it. NEVER DOUBT ANGSTROM RESEARCH CUBES

Alright, first of all, if you need a upgrade from your UM, do it, get this cube. But if you already have a sm but not from thecubicle premium, don't buy it. But it is your choice and here is my review:

The cube is fast and controllable. Out of the box, it is slow which is expected. The cube have a feeling that cannot be explained, it's like scratchy but not at the same time. What ever it is, it is a great cube, it made me break my pb which is now 17.36! Thanks again cubicle for making this awesome cube

Out of the box it had a slow and controllable feel which I didn't really like. But, then I did maybe 20 solves and it became fast, smooth, and bubbly, especially with some lubicle silk.

That cube is beyond my expectations... I have no words except wow!
It's pricey, but if someone can afford a video game, that cube compensates for its price and offers unlimited game time :P
