Review on 6-Pack Speed Cube Set: 2X2 3X3 4X4 Pyramid Skewb Ivy Stickerless Puzzle Cubes - Perfect Christmas/Birthday Gift For Kids, Teens & Adults! by Thomas Unruh

These puzzles have kept my kids busy for many many hours. As I've used them (and been frustrated with finding their solutions), I've really enjoyed the smooth action and quality tactile clicks as the pieces are moved. I really think this is a top-notch set.LIKES:• Soooo many tough puzzles!• Seemingly high quality. Survived many drops.• The surface material is a nice satin feel, yet solid.• Variety. each puzzle is a totally different beast. You'd think the two by two cube would be easy. think again.• Hours of entertainment for boring meetingsDISLIKES:• 5-faced cube is a little loud with its clicky-clacky-ness. Not great for said meetings.• 3-face cube is fun but too easy to twist, and really easy to solve.
