Quite a fun puzzle - it's a shape mod of the now-popular Face Turning Octahedron, but solves quite differently due to how the pieces are identified and different ones being interchangeable, at least compared to Bencisco, the typical speed method for FTO. Turns as well as you'd expect from a LanLan puzzle: smooth plastic, little corner cutting, and occasional pops, but you don't have a better choice for a Rex Cube anyways. Would recommend if you're interested in a simple enough yet intriguing solve, especially if you've been doing FTO already.

This puzzle can be a little bit stiff out of the box, but breaks in nicely. It has a heavier plastic, so you don't have to worry about that "cheap" feeling some puzzles have. I have no complaints about the stickers. It is probably a 5/10 as far as challenge. As you can see by all the other comments, this cube has a very fun, satisfying solve. Mostly due to the fact there is only one algorithm needed, and the rest is all intuitive. If you are new to cubing, or you are looking for something new with a small learning curve, I would highly recommend this.

The Rex Cube is a very fun puzzle and quickly became one of my favorite cubes.

The quality of the puzzle is very good. However, the triangle pieces will sometimes pop. It's annoying when it happens, but they're easy enough to put back in and doesn't ruin the solve.

By far my favorite puzzle in my collection. It turns well and is a good quality of plastic. Only major downside is the stickers aren't as good as the could/should be.

This skewb is one step up from the standard skewb and a step below the master skewb (it is a rex cube with rotating corners). I find it very fun because besides essentially 1 alogorythm, it is soved intuitivly. As for the quality: it is low. The petals often pop. They are quite easy to push forcefully back in. The turning can be rough and helped slightly with lube. Also it can catch if not lined up exactly right. I like the colors: they are like traditional shengsho colors. None are flouresent.

The turning is tremendously wicked but I expected it. Stickers are cheap but once again expected. It is a fun puzzle to solve as long as the tight turning doesn’t bother you.

That being said, it’s a classic and with it being a classic you can feel the design’s age with every turn.

I learned about this puzzle a very long time ago from CrazyBadCuber, I bought one 7 years ago and it broke... Sk I got a new one just the other day :) The turning is a bit stiff and the stickers feel cheap but that is ok because it is a really cool design and is fun to figure out intuitively.

Very stiff and slow out of the box - needs a lot of breaking in before it gets good.

Fun to solve though!
