### ⭐⭐⭐⭐⭐ Makes a great gift
*by J***  on July 25, 2025*

My 11 year old son spent hours and several days putting this motor together. The end result of his excitement when he heard it run and to be able to shift through gears was the absolute best. He has a very mechanical mind so this was an excellent birthday gift for him.

### ⭐⭐⭐⭐⭐ Well Worth Buying
