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.

A fun puzzle, but it may need work.
Both the original puzzle and its replacement became unusable the first time I started to solve them.
The Orange (0 face) center became stuck; turned about 60 degrees (it shouldn't turn at all) on both puzzles, rendering then useless.
However, after almost giving up, I found that by carefully adjusting the tensions in the core I could get the puzzle to work.
