Review on 🚗 Keenso Car Rear View Rectifier with 12V DC Power Relay Capacitor Filter Connector - Optimized for Backup Camera, Auto Car Camera Filter by Chad Black

None. No work! Maybe a fancy box, but very cheap components. I'm an engineer but I was in a hurry so I just bought this. It failed quickly. I ended up taking it off and doing it myself. I ended up wasting more time trying to avoid work and buying this. My opinion is not normal typical because I am an engineer. If you don't know anything about electronics, this could be the solution. But if you can solder, then assemble it yourself, google the diagrams. These are just some of the components you can salvage from old electronics like a remote control car, old computer parts, even old speakers or radios, etc.
