I've solved many "harder" puzzles before, but not this one yet! I think I know solution, but my algorithms are not very efficient so it solving is slow.

Unlike other reviews, my puzzle has never popped! I'm not afraid to say it (as some other of my reviews do). I don't know if DanYan improved the mechanics or prior reviewers got a "bad batch".

In fact, this is one of the few (only?) puzzle that I give full 5 stars. Things I like:
* 6 classic colors of original Rubik's cube (in the same orientation)
* Sticker quality is nearly perfect (I can't think of any flaws, but there might be some very minor ones)
* Size and weight nearly the same as classic Rubik's cube (good!)
* Each face has 8 facets, one less than standard Rubik's cube, but there is no fixed center, so arguably same
* Very challenging, at least for me
* Turns smooth out-of-the-box (even though it seems not lubricated)
* Nice price (not the cheapest puzzle, but there are more expensive puzzles with worse performance/quality)

The bad:
* Will sometimes lock-up, especially if you get in a hurry (I don't think lube would help, but haven't tried)
* nothing else :)

I guess if you tried to aggressively turn it like a speed-cube you might pop pieces? After spending a few days trying to solve it (without success) I decided to take it apart, to see how it works and start over from a "new" state. It took considerable effort to get a piece to pop to begin disassembly. WARNING: if you try this, only remove a few pieces at a time! After removing 6 to 8 pieces (as I recall) the entire thing will disintegrate, and is a REAL challenge to re-assemble.

Hints/suggestions: this is shaped like a cube, but has 4 axes of rotation, like a tetrahedron... in other words a disguised (master)Pyraminx! I strongly suggest you master the basic Sqewb first! I can solve that, but this one is still a challenge. I guess if you can solve this easily, it is time for the Master Sqewb? This one actually costs more than Lan Lan Master Sqewb, but I haven't bought that yet, so it may be worth the price?

Anyway, I love it, and recommend as either good challenge or a nice addition to a collection.

It's a very good puzzle. Popped once, but only because I was sloppy. I would like to note that the stickerless version is slightly different from the stickered version so please consider the following before you decide which you would like:

Just as I suspected, this also has an additional solve component similar to the Dayan Gem V stickerless version. However, the additional solve component might be considered optional with this puzzle, given it is harder to see the internal pieces. In the picture below, you can see that there are internal tetrahedral corners and edges. In a TRUE 100% COMPLETE SOLVE, these tetrahedral corners and edges should all match as well. If you don't deal with these internal pieces at the start of the solve, be warned that the completed cube will have mismatched internal colors that are just slightly visible.

I got this puzzle a while ago and its pretty nice! It currently stands as the hardest puzzle in my collection (its pretty hard). My only problem is that it pops ALOT. If you dont know how to fix it, then you need to learn. Explosions are also a possibility, but overall, I like it!

I got this cube from a friend for christmas, and when i saw it I was very excited. right out of the box i thought it was great except for the turning, when i turned it and it popped. It was a pain to put back together, and has popped several times since. its not a terrible cube, but i would recommend spending your money on something a little more reputable
