Grandson will enjoy this at Christmas

Review by my 10 year old: This toy is ok. When it worked it was very cool and the directions were easy to follow. It took a super long time to get it to work and when it did work, it did not work that well. We figured out at some point that it was because of a tiny bump on one of the gears that was preventing the parts from connecting the way they needed to. We fixed it by filing off the bump with a nail file. The head of the toy also kept coming off and is super hard to get back on. In the directions it says to put the black wire on negative and the red wire on positive, but you actually needed to do it the other way around for it to work. After we had made the main part, we started making into “dog-bot”, which was listed as a level 1 build (that should be the easiest level) but making it was very hard to do, and it said when you turn one piece it would make the gears move but it did not. While I had fun when I got this toy propelling itself on its own solar energy, I would not recommend it to anyone without a lot of patience.

The pieces simply DO NOT fit. I even considered using a soldering tool but the defectiveness of this toy is superior to any skill or tool a parent can try to apply. In the box already to be returned. Please check photos and video if you are still considering this item.

Got this for a gift for my grandson who is now the age where they enjoy taking apart and putting back together everything they get their hands on got this as gift to help with STEM and preteen engineering minds best money every spent in gift he loved it and built and rebuilt this multiple times to make most configurations

Let me start off by saying it's not easy to put this together , it takes some patience and a lot of Youtube Videos to know how to assemble. Just search for the videos , there are lots with easy step by step instructions.Once it is assembled, it works brilliantly and there are different toys you can make with it.Pros :Great STEM toyLots of different varieties of Solar powered robotsMany online videos with clear instructionsCons:Needs a lot of patience to assemble
