This is a good cube. Everyone says it is small, but I was still surprised by how compact it is. At the narrowest part, the edge length is similar to that of a Pyraminx, and it is around 10 millimeters larger at the center. It is fairly heavy, at 1,080 grams, or about 12 times the weight of a GTS3 M. The size improves solving comfort, but it is still fatiguing due to the weight. Turning is okay, but not great. It is fairly stiff, but it gets better with use. The main issue regarding turning is that the puzzle is quite rigid, so the layers need to be aligned before other turns can be made. This combined with the pillowed shape means that some lockups are to be expected. I have gotten two pops so far, but both were due to inaccurate turning and could have been avoided. Solving this puzzle is enjoyable, but also repetitive. It is not something most people will solve often. This cube is extremely well-built. I have no concerns about durability, but the stickers chip easily, so I do recommend the stickerless version. There are slight blemishes on some edge pieces, but nothing very noticeable. There are also unsightly seams on the innermost edge pieces, but the stickerless version avoids this due to the adjusted mold. Overall, this is a good puzzle, but it does have some issues. I do recommend it, but only to people who enjoy very long solves. I would suggest that most people opt for the YuXin HuangLong 11x11. It is much cheaper, turns better, and is much less tedious to solve.
