Review: As described worked great - Worked great 👍
Review: Build surprised well ! - Only purchased this for the main controller and end up using all the pieces and switches due to them being better quality and more Kid Friendly. Accidently put 24V to it and reversed polarity and it's still working like a champ. This kit is great for any vehicle pretty much (even homemade), it comes with everything beside the vehicle and battery. I'm really impressed with them.

### ⭐⭐⭐⭐ Good, but not plug and play
*by N***S on October 6, 2024*

I used this kit to repair my child's ride on toy that had a bad controller board. Because it was an off-brand there were no direct replacements so I decided to just replace everything. Overall, it seems better made than what the car came with. However, a wiring diagram should have come in the box rather than just the Amazon listing. Unless you have a model very similar to this one, this is a kit for someone comfortable crimping/soldering wiring terminals. Mounting the switch gear and running new wires is a project in and of itself. The end result seems good. I'm also running an 18v power tool battery conversion kit and it seems to handle it just fine.
