Rubik’s Phantom, 3x3 Cube Advanced Technology Difficult 3D Puzzle Travel Game Stress-Relief Fidget Toy Activity Cube, for Adults and Kids Ages 8 and up

I bought this for my teenage nephew for Christmas who is an expert Rubik's cube fanatic and it kept him entertained for quite a while, amused by the disappearing colour challenge. Several weeks later and he is still playing with it, though not as often of course, having mastered the initial challenge.

This phantom cube is quite tricky to find in the UK but that's no reason to pay £38 + nearly another £10 delivery, get one from Smyths for £23. However, be warned this is not a good quality cube and it's too pricey for a novelty. Poor quality plastic, no magnets, rough edges, variable gaps between the tiles and the plastic of the cube. A real let down, an idea full of promise but an abject failure. Rubik's should be embarrassed to put this out at any price.
