Our Promise to You

All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.

Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

Pretty decent, but has flaws.

First off, this is the only mirror squan I've seem, so if you want one it's a good deal imho.
However, due to having 3d printed extensions it's kinda big. I also found it to be a bit too loose, but the extension prevent you from opening the underlying mechanism to adjust. I managed, but turns out the default tensions are pretty sensible if you don't want parts rubbing against each other.

I also found a minor design flaw. You know how puzzles often use springs on a screw to tension the puzzle? Well, when you pull the two square-1 halves apart too far the spring can slip into the core, losing its power. I managed to disassemble the puzzle, carefully get of the extension to reveal the screw and put a in washer to prevent the spring from slipping inside the puzzle. Bonus points, I can play with the tension now.
Won't happen when you don't try to pry the puzzle apart to disassemble, but if you do, you should take care of this as well.
