Absolutely brilliant BUT!
It’s common sense really but we popped these back in the box after playing with them and forgot to take batteries out, the wires crossed and melted!
Luckily my then 8 year old caught a wife of the smoke and sorted it.
Just be careful!
Excellent value for money
There are 6 motors with battery holders and a host of gears which is excellent value for money. Because you do not get a heavy torque the plastic gears are reasonable for small projects. There are enough gears in reasonable ratios but it would be nice if the wheels had the number of cogs written on them.
I brought this kit to help introduce basic electronics to my 6 year old daughter, and we have had some fun with this making a fan and a small car (and have a few more ideas planned). However if you have no knowledge of electronics at all then you might struggle to get anything working. What would have been great is a small leaflet with some example ideas complete with instructions to help get people started, but sadly it does not.
Secondly the Battery holders are very poor quality and do not hold the batteries in well at all, often falling out. So we had to use some tape to keep them from popping out.
Used this for a school project to make an electric car. Tried a lot of versions – looks very simple online but in reality was a bit tricky. Connecting the fan seemed to be the easiest way to get it moving. It’s all easy to use and kids can do it (with supervision).
