the puzzles are good but have downsides...
2x2: really good but just not enough to compete
3x3: no offence but the 3x3 is horrible it is just bad and has weird marks on the inside
4x4 really good just really dry and not too good like the rest
5x5: generally fine, just too many better options.
all in all its overpriced and is not too bad
