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.

Fun puzzle

Very fun puzzle, and it's a bit more challenging than it looks. I highly reccomend it. It had multiple deep scratches on the surface and a ton of spring noise, which caused me to take a star off, but otherwise it was very well made and fun to solve.

Very good!

This turns very smoothly and well! Quite a bit more challenging than a regular mirror cube, but that just made it more fun. I have no complaints with it.

Nice cube

This is a very smooth and pleasant 3x3 shape mod.
