The Carl's Bubbloid 5x5x4 is a shape-preserving 5x5x4 corner-turning cuboid developed by Carl Hoff, David Ang, and Calvin's Puzzles. It has a very sturdy, substantial feel, and it features the Calvin's and Carl Logo.
Please be advised that the puzzle as it is shipped from the manufacturer does not have much corner-cutting ability, although it does turn well when it is aligned properly. The manufacturer has noted that removing the springs from the corners will improve the corner-cutting on this puzzle.

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.

This moves a lot like a Redi type puzzle, with radial turns.
I did have an issue with popping and very loose pieces. This eventually led to one corner falling apart, then the side and eventually the entire cube pretty much was reassembled.
My cube has been put back together and it works really well.
I just wonder what caused so many pieces to be so loose OOTB.
Regardless, I think that this puzzle is great and man, does it look fantastic.
this cube is extremely hard to turn
