Review on LAFVIN Smart Robot Car 2WD Chassis Kit with Ultrasonic Module R3 Board: Arduino Compatible DIY Kit for Remote Control Programming by Alejandro White

I had a terrible experience with LAFVIN customer service with this kit. I needed an Arduino to work on this kit so I could do some lab work for school. I tried emailing them and they quickly shot me and told me to download the drivers after I was sure they didn't. Overall, this product had a lot of cheap parts. I had to re-solder the negative to the battery case and the wires easily fall out of the motor controller. The building instructions are lackluster and I hesitated to settle on a design. I wouldn't recommend LAFVIN just for the customer service aspect. Don't expect them to help you if something goes wrong.
