This is quite large - I know it gives the dimension in the description but even so I wasn't expecting it to be as big as it is (I have a mirror 3x3 which is the same size as my normal 3x3) this is quite a handful to turn. The quality of the build is good but you have to focus on lining up the sides else you spend more time trying to turn a side, catching, lining up, trying again, catching, adjust a bit ... oh forget it, I'll try and turn it the opposite because .. yep that works .. oh now I've lost where I was in the algo. I didn't expect a speed cube of course but nonetheless, I had to really slow right down each turn to line it up and this can become mentally draining after a while.

However, all that said, I am enjoying the puzzle. A lot.

There are no other mass produced mirror 4x4's on the market (at least I have not found any) so if you enjoyed solving a mirror 3x3 and can solve normal 4x4 then get this. You'll have so much parity you'll learn to love it :) (which centre goes where and opposite to which?).

Now if only someone would do a fisher 4x4 mirror version.

It's not what I was expecting for the price but honestly I can't complain. It is a mirror 4x4 that turns with the same quality as a Shengshou 4x4 but maybe twice the size. While it's big and finicky, I think that for those who want a harder (and I mean much harder) challenge from the mirror blocks, this is a good step.

I love this cube, but it feels very delicate. Like it could fall apart if it got locked up and someone was trying to turn it fast. The cube moves really smooth, minus the catches. Lots of fun! I would be highly interested in a more stable version of a 4x4 mirror cube.

I couldn't be happier with this puzzle, it's so much fun and with a combination of your fave lube it becomes even smoother than seems possible for such a complex puzzle. You won't be disappointed.

Normal mirror cube is easy for me, so is a 4x4. Mix them and the result is... pretty hard?
Solves exactly like a 4x4, but due to the lack of colors getting pieces into the right place is pretty tricky!
This cube is partly 3d printed, and you notice that. It is considerably bigger, pricey and the turning feels a bit scratchy at times. Might need some breaking in.
Also, did I mention this is the only 4x4 mirror I found? I am thankful to whoever made that, worth the money to me!

I didn’t read the description so I was surprised when I seen it was 3D printed. Not mad at it at all. Turn very smooth. Will get another in a different filament color.

I am pretty pleased with this, however. I am slightly disappointed because it is 3d printed, that just means it's harder to turn.
Other than that, difficult to align layers (not bad) but turns really well. No corner cutting whatsover. A neat twist to the standard 4x4 cube, and way harder :)

Kinda Scratchy to turn
