### ⭐⭐⭐⭐⭐ This has upgraded ,
*by E***T on September 4, 2025*

Fantastic product!I replaced the old motor with this.The bearings and metal gears look so much stronger.I'm running 18v ryobi with a step-down module to 12v.My grand kid beat the original in 45 mins!Stop and go kills the original gearboxes. So far it's lasted 2 days!

### ⭐⭐⭐⭐⭐ Fast motor replacement
*by V***L on December 10, 2024*

Upgraded the car to use 20V batteries. Soon the gearbox wore out and this was a better replacements. Not sure how durable. Will update reviews over time.

### ⭐ These suck.
*by T***G on March 18, 2025*

These motors burnt out in less than a month, and the torque on them is sub par. In grass the barely took off. Once it got some speed and momentum they were okay. But for a 25lb and 35lb kid. These were terrible.It started smoking and almost caught on fire.
