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.

Quite enjoyable!

Pretty fun solve! Not too easy, but also not too hard -- you should be able to figure it out if you've solved a cuboid before; the methods don't exactly correspond but they're similar. Locked up quite a bit at first, especially the side with the locked circle (yellow I think), but it turned out it just needed to be broken in. Still a little hard to turn occasionally, but since it's not really meant to be speedsolved anyway that's fine. I've been playing with it quite a bit since I got it, and I am now curious to see what the differences and similarities are in the other Crazy Pentahedron solves (the Mercury is the only one I bought), so I'm putting the other variations on my wishlist (unless I decide to buy them on my own first).
