ShengShou Mr. M Square-2 (Magnetic)

This cube is enjoyable to solve and a fun puzzle to pick up and twist. I especially liked how you can do portions intuitively but can also weave in square-1 algorithms. I was pleasantly surprised to find out it had magnets in it that help it turn very nicely.
Unfortunately, the puzzle is designed poorly such that there is only one **** holding the core together, instead of two like you would see in a normal square-1. In combination with the orientation of the ****, this means that as you turn the puzzle, the **** progressively loosens until it falls apart. I had it fall apart on me three times before I superglued the **** in, which fixed my issue but that means you can't adjust the tension (but it's not a speedcube anyway, so that's fine).
Overall, once the design problem was fixed with superglue, this is a fun novel cube that I will probably pick up from time to time instead of leaving it on the shelf.

The cube feels nice and all, but it seems to get unscrewed from normal usage, causing it to fall apart frequently.

Very difficult but very impressive

I own 15 other twisty puzzles and never had one pop on me even one time. I have owned this for about 3-4 days. It popped the very first time I used it and I had to put it back together having never put a popped cube together and without any videos showing how to do it. I got it put back together and figured out how to solve it pretty quickly having already (mostly) mastered the Square-1. Its fun with the extra layer of difficulty.

Problem is I felt like I needed to be very gentle with it. And after about 5 or 6 solves it popped on me again. Not a huge deal to put it back together but I don't want to have to go through this every few solves. Based on another review here it sounds like a design flaw. I know that they super glued something to fix theirs but whatever it was was censored out in the review so I am not sure what they did.

I am thinking maybe I should probably look for another version of the Square-2 without a design flaw. Which means I would also not recommend this.

I've given this cube a few spins and I like how it moves and feels in the hand. I know it's going to be an extra challenge after mastering the Square-1, because you can slash right through the corners. Can't wait to scale this mountain!
