I really like this puzzle! First off, note that this is NOT the same puzzle as a master skewb. It looks identical but turns and solves differently. 4 corners turn with shallow cuts, and the other four have deeper cuts that turn like a master skewb (as well as trivial tips). This is a moderately difficult puzzle that has elements of many other corner turning puzzles such as a skewb, dino cube, rex cube, FTO, and even pyraminx and master pyraminx to some extent. After a little effort, I was able to figure out how to solve it. I can now solve in with a couple different methods. After playing around wiht it for the first 15 minutes or so, I had a major realization about this puzzle (although it still took much longer after that to solve it). I won't go into details on what this realization was or how I solved it. If you want that you can go on Youtube and find a tutorial. I'd say this is basically the same difficulty as a rex cube or FTO. It's not a puzzle for someone brand new to twisty puzzles. If you're comfortable solving other mid-level non-WCA puzzles, this should take a bit of thinking but not be insanely difficult. In order to solve this, you need to know how to solve a dino cube and a skewb, and be comfortable with basic 4-move commutators (A B A' B') and conjugates/setup moves (A B A', where B is usually multiple moves, and A sometimes is). You don't really need to come up with any of your own algorithms, or use any 8 move commutators. Turning quality is perfectly adequate for a non-speedcube. The puzzle has no issues with turning as long as you're not trying to speedsolve it.

First off, be warned this is not the same puzzle as the Lanlan master skewb. This is essentially a master F-skewb. That being said, if you are a non-wca lover or collector, this is must have. It is a stable puzzle. It has a dayan feel (lighter plastic) and the turning is good out of the box. To solve this you will need to be able to solve a skewb, dino cube, Rex cube and know commutators.

This can take a bit to wrap your head around just how it moves and what puzzles it can be reduced to -- it's not intuitive at first but once you start diving into it and figuring it out it's a very rewarding solve.

I'd recommend this to anyone who has experience with a bunch of other non-WCA 4-axis and 8-axis puzzles. If, however, you just learned to solve a skewb and are looking for something "just a little harder," bookmark this one and come back to it later, get some experience with a rex cube and maybe a master pyraminx or even an FTO and then take on this one — this one is the kind of puzzle that I think you're going to enjoy more if you're able to come up with your own solution rather than falling back on a tutorial.

Turning quality is good. It'll catch at times but nothing that should impede your solve.

I knew when I bought this cube that this wasn't a normal master skewb, but I wasn't ready for the weird turning of this cube. It will surely be a fun solve. The turning is very good out of the box.
