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

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 have both Elegoo and Uctronics. Elegoo is the best - comes with videos, easy instructions and everything works (I've bought several kits with no problems). They seem to have been so successful that Uctronics and Lafvin copied them - made cheaper versions - and you get what you pay for - as others have said: 1. No clear wiring (good luck it actually works). 2. The battery box is not the right size (looks like the box is 3D painted and too small for the batteries. All in all, buy Elegoo! Do not

A few days ago I received a Lafvin robot car and started assembling it. The instructions are a bit weak for a beginner, but you can handle it. For $ they can't be beat. What disappointed me the most was that the kit is designed for a pair of 18350 batteries, which are not that standard in the US. I replaced it with a Revain 6 cell AA battery. I built 2 other VKMaker cars that basically had the same components but much worse instructions and no useful code (I had to find the code from the links…

So many problems with this set. I've built several other robot cars from China so I wasn't expecting it to be very easy to follow the instructions but this one was really bad. There is no clear schematic in the whole set. Instructions. Many of the instructions are for the 4 wheel version of this kit. There are different lessons for IR sensor, wheels, ultrasonic sensor. They reuse the pens in different lessons, so it's impossible for the code for the ultrasonic sensor to work at the same time as
