First of all may i say that I'm pretty good at this toy.. averaging 30 second solves. Therefore i am obviously an advocate of it and think it is extremely fun, challenging in a positive way, and educational as a mathematical (logic) puzzle.
However, I have not rated this product as highly as i would have liked because this particular branded cube is not particularly great.
OK fair enough for a total beginner just wanting to learn the basics or as a gift etc etc (basically not as a serious buy) it is an far product... does the job. In fact this was my first Rubik's cube, as I am sure is true for most people.
The build quality of Rubik's Rubik's cube is shoddy. As many other reviewers have stated, the stickers peel off easily with use. They are double layered, with a sort of cling film type sticker over each colour, however this just served to annoy me as i had a whole cube of stickers with half peeled off see through stickers, then as it deteriorated further the actual coloured stickers peeled off.
The actual cube structure is basic therefore the cube does not spin nicely. I am yet to encounter a cube of this sort which can maximise solve times. Mine was poor despite proper lubrication methods. If you are already good at solving, or plan to get good, you should buy a cube from one of the many website which sell DIY cube kits which have much better build quality and sticker quality.
Overall i love the Rubik's Cube, not this actual product however.
