I recently purchased the Elegoo Smart Car V4 with Camera from amazon website as a gift for my son.L as it's a wonderful educational tool and a great introduction to robotics. Unfortunately, our experience has been disappointing due to a faulty Ultrasonic Sensor. Despite following the assembly instructions and troubleshooting steps carefully, the sensor does not function at all. This has halted our progress and taken away from what was supposed to be a fun and inspiring learning experience for my son. I am kindly requesting a replacement for the defective Ultrasonic Sensor so we can get the Smart Car fully operational. I hope this issue can be resolved quickly. Thank you for your attention, and I look forward to your support.

Received as described. Excellent product, items quality is excellent, I have assembled it with my 12 years old son. He enjoyed a lot. It worked perfectly after Assembly. This product is worth for money. Highly recommended.

totally recommended. I had a lot of quality time with my 6 years old son , assembling the robot. It's way better than any remote controlled tank, let alone the ability to teach your kids robotics and programming

it s very good item to our child who are interest to assemble the products. it is helpful to improve our kids knowledge. wonderful item.

Fast delivery. Easy assembly. Pre-Programmed. Functioning perfectly. Doesn’t require wifi connection. It creates its own wifi. Easy mobile application.

Good for kids

The base/top plates are sturdy, even though they are plastic. Instructions are clear enough to understand and assemble. The UNO comes pre-programmed. So once you assemble it, you can start using it like a toy. App control is seamless. All default functions work well. I haven't figured out yet how to customize the programming, for example, do various other computer vision tasks.

This Smart Robot was my introduction to Elegoo products and the experience has made me a diehard fan of Elegoo. I bought this for my 9 year old son as a gift for the holidays. This was my attempt to give him gifts would peak his interest enough to get him away from all the games and electric devices and this did the trick. At first when I first opened it I wondered if it was to much for him to assemble but boy was I worng. He enjoyed every moment of it and has not stopped using it. Its so much fun that everyone in the house is enjoying it. It was designed and packaged so well and the instuctions were very easy to follow. Love the care they took and the packaging was neat and well organized. In its default state its packed with features but the intro to Arduino IDE increases its value immensely making it possible to add more components, features and functionality. This has already paid for itself times over and its value for money is undeniable!!

Excelente juguete didáctica y aun lo que “nos falta”. Aprender…

Very nice
