### ⭐⭐⭐⭐⭐ Good quality

Excellent item. Fun to put together

### ⭐⭐⭐⭐⭐ Great puzzle to keep the grandkids occupied .

Great puzzle to keep the grandkids occupied

### ⭐⭐⭐⭐ Instructions could be better.
*by G***S on 2 October 2025*

I had fun putting this together, not to hard, the one page instructions could be better but I was able to follow OK. You don't "need" glue but a couple of drops in a few key places, like the bottom of the ZigZag don't hurt. The solar cell is a nice addition but changing from battery to solar means dealing with a Very small connector. Plus solar you need well Sun light. All in all good and I'm happy with it, I probably will get more kits from them in the future.
