As a gift for someone, this is perfect. In a box designed to store each one, which is really nice. Great value for money as well. There are diagrams of how to put each puzzle back. Is really worth getting.

Brilliant delivered timely & the puzzles kept my husband & child entertained for ages.

Excellent -- bonus -- has all the solutions

My dad had some of these puzzles when I was young. I have bought these puzzles to keep my mind occupied. Excellent value for money. They are quite stiff at the moment but when they have been used a few times to get will ease.

Difficult enough to be fun for adults, however the instructions are awful, so after a couple of days I haven't even worked out how to get one of them apart yet! A couple are so tightly slotting that my children (10 and 12) really struggle with the force required to push the pieces together and some need a level of two-handed dexterity to hold multiple parts loosely together while also inserting another, that they are beyond most young children, despite understanding the technique.Good, but the precision cutting is lacking and instructions are useless.

My son brought this with his Christmas money, he loves it. Keeps him focused and enjoys handling and trying to solve the puzzles. Had a slight problem with one of the puzzles and the customer service was excellent in sorting this out. Would recommend for adults as well there very addictive.

Some of the pieces were OK, but there were also some that couldn’t slide against each other at all, when intended. Poor quality. Takes all the fun out of the game.

Good product, will be purchasing more
