The ShengShou 11x11x11 puzzle is an amazing puzzle. It is very smooth and turns effortlessly right out of the box. When I got mine it was quite loose so I tightened it. The puzzle didn't pop when it was looser but I thought it felt too flimsy. (It was still really stable) Now the only bad thing was the quality of the stickers. When I opened the box almost every side had a few stickers that were a bit folded and dinged. One side even had some chips. I have replaced the stickers now with the extra set (just the bad ones) and they have not chipped or peeled at all I am not sure wether this was an issue with the company (ShengShou) or if it was the mail. I have seen the same issue with the stickers in a few unboxings from other Youtubers as well. Overall I would highly recommend this puzzle to anyone who likes big cubes. I also find the price perfectly reasonable. I know this was long but thanks for reading!
