This set includes so many fun cubes! Plus they look super cool. Some of the cubes are better than the others though. The pyraminx and skewb are actually great quality and look good with the carbon fibre stickers. On the other hand, both the 4x4 and 5x5 tend to pop quite easily if you're not careful, and if you plan on solving them a lot, it might be worth it to take the stickers off (they're stickerless cubes with a good colour scheme) of them so you can easily identify the colours. As well, the 2x2 is just amazing for the price except for the colour visibility, with the stickers on it is much harder to speed solve. The other cubes, the megaminx and 33, are all around decent budget cubes, not much to comment on there.
All in all, this set is a great bargain for all you get and I would highly recommend it to anyone just getting into cubing or looking for some cool looking twisty puzzles.
