Review on SunFounder Raspberry Pi Smart Video Robot Car Kit V2.0: Explore with Graphical Visual Programming Language, Pi 4B Included by Mark Adlesh

As promised, here is my updated review: They had excellent customer service to replace missing parts. The parts were sent immediately. It took me two weeks because it comes from China. But I was finally able to assemble the robot. The rest of the build went smoothly, although mounting the camera is a bit tricky. I managed it after several tries. Also, the instruction sometimes had to be interpreted due to incorrect English. After assembly everything was great. It was easy to install the OS and code from github, connect via Wi-Fi, and the API was very easy to use. Their client was easy to use for calibration and also served as a good example of Python code to create my own automated robot control software. Just make sure it comes with hex front wheel lock plates now. Additional Tips: You will also need two 3.7V 18650 Li-ion batteries and a charger for these batteries. Even if you get the version of the product that comes with a Raspberry Pi and a micro SD card, you may need an SD card adapter (to boot the OS from a laptop). And you need a Raspberry Pi charger (only during installation. Runs on batteries afterward). Original review: I got it today but I can't even do the first step of assembly because it didn't come with a hex. Mounting plates for front wheels. I don't see an option on the seller page to ask a question. I would rather have the parts shipped to me than have to send the whole package back. I'll be happy to update the review when I can get the parts.
