I am thrilled with these puzzles. I have bought them for a Secret Santa. Can't wait to see the look on the recipient's face.

The puzzles are well worth the price, in theory. The practice is something else. The instructions are more hints than instructions on how to put the puzzle together. The diagrams are less useful than pictures and exactly what they are showing is too often very open to misunderstandings. The manufacturer ing of the puzzles is a little to loose to help the process. This means that for the cube you end up trying to hold three sides simultaneously. A difficult to impossible task.I think you need two people for these to work really well. You cannot hold the pieces in place and insert the next piece if the pieces you think you have added start to slip or move as you do so. Extreme difficulty is a feature of these puzzles.I think I need to return them. I have had other puzzles of this type and the manufacturing quality was not such an issue. Complex puzzles could be done without needing extra hands.

This was bought for my son he loves puzzles...they are harder than they look..great way too pass the time and get the brain working...

It takes about 5 minutes to solve it all.

Very strong indeed, lovely design. It's a challenge and fun with children, like very much 💯
