### ⭐⭐⭐⭐⭐ Great Metal Puzzle.
*by E***8 on April 6, 2025*

You will need to buy some special tools. This was a 7 out of 10 on difficult level. Overall it was alot of fun. This was my first metal puzzle and I made a few mistake but overall I think it turned out good for my likings.

### ⭐⭐⭐⭐⭐ Loved it
*by E***Y on February 20, 2025*

LOVED this puzzle. Such a cool build.

### ⭐⭐⭐⭐ Not great for beginners or kids
*by T***N on October 22, 2025*

NOT for kids. This is a puzzle meant for adults with lots of patients and I would not recommend this for beginners. The pieces are super small and some tools are recommended prior to diving in. Luckily, my husband is REALLY into these type of model puzzles and loves tinkering with these type of things. He can throw these together in a couple of hours making it look like a cake walk while mine end up with tiny lost pieces somewhere in the carpet and the rest half assembled in the garbage just before I go plop down in front of the TV with a huge glass of wine. Quality wise, the pieces are pretty fragile, but once it all comes together it seems pretty solid as a unit.
