Guaishou 10-in-One 3D Small Wooden Puzzles Kongming Lock IQ Test Toy for Teens and Adults

These could be so much better if the construction has less of a tolerance issue. The puzzles are very loosely held together, so once they are dessembled, it's extra hard to put back together.I won't gift these to my friends knowing that it will probably create quite a bit frustration.

Unless you have hands the size of a five year old, I don't know how any adult is working these puzzles. Nowhere in the description did I see the dimensions or I would not have purchased. In the process of return. Not only are they small but they don't look to be very good quality. I did not unwrap or attempt to use.

I was really satisfied with this purchase in general but some of the puzzle pieces weren't totally complete, still solvable but REALLY hard to hold in place even when the solution is known. Only effected the puzzles that had three pieces intersecting in the middle. I mean, these are cheap so I get the corner cutting. Still worth the money.

The pieces fit extremely loosely, such that the puzzles will fall apart just holding them. Some of the pieces have chips. The pieces for one of the puzzles fit actually fit so tightly you can barely take it apart or put it back together.

I put these in everyone's stockings this year, and while my kids are still young for it, it was absolutely perfect. All the adults were working on these for quite some time, and they are very fun! The kids liked that they had their own, even if they couldn't figure it out yet. They were certainly a hit. I highly recommend them.
