4pcs/Set Children DIY Assemble Solar Power Car Toy Kit Science Educational Gadget Hobby

Great value. 4 car sets included. Instructions are in Chinese but the pictures are easy to follow. Has small parts ... kids would need supervision.

I bought 12 kits for my fourth grade students. Before using them in the classroom I put together one to try it out. The instructions are not in english, but with the pictures and common sense you will be able to figure it out. There were several parts that I decided to do ahead of time for the students to save time and confusion. I also discovered these only work with VERY BRIGHT sunlight. Indoor light will not work. I even bought a sun lamp in hopes it would work, but no. The students enjoyed putting it together and it was challenging enough to make the building part worth while. However, six out of twelve cars broke when the wires came loose. Out of the other six, some were able to adjust the spinning components and get it to work - which was very exciting for them. I had my husband solder the wires back on for my next group of fourth graders, but four out of twelve wires came loose when they tried it. In the end, it was a great idea with serious disappointment. I would only recommend this if you are working with the one to three kids or just by yourself.

I bought these for my classroom because I have no budget. We haven't had a chance to test out the solar charger yet, but in assembly we learned a few things. The instructions include pictures, but the directions are not in English. I'm pretty sure they're written in Mandarin. I was able to assemble the car using the pictures only, and my 5th graders were able to also, with some guidance. The materials are cheaply made and are very fragile. One group of students unintentionally broke two of the solar chargers by separating the wire from the spot it's supposed to be connected to. I would most likely not buy them again. I mean, you get what you pay for...

I just love it, it was fun to assemble, yes the instructions are in chinesse but image are perfectly clear and just watching them you can assemble, i bought it for my son school project and it works excellent.

I bought these to put together with my kids and their cousins to have car races. The kids all loved them and were able to put them together with some help from me. But they didn't last more than a few days, so keep that in mind. They are cheap/delicate.

Easy to assemble but if you screw the tiny screws in all the way, they block the axle. And only 2 of the 4 solar panels worked.

The media could not be loaded.  Nice they work good. I ended up adding two motors in one. Don’t put the wheels to close to body or else it won’t go. Make sure you can freely spin the wheels before adding motor and solar panel.

Instructions are only in Chinese. Parts are VERY small and hard to handle. Once built, it did not work unless we angled it perfectly in the sun. The problem is that the surface was flat so it did not go. A frustrating and cheap product. I do NOT recommend.

Desafortunadamente, ninguno de los cuatro coches funcionó. Seguí las instrucciones cuidadosamente y aseguré que todas las conexiones estuvieran correctas, pero los motores no se activaron, incluso bajo luz solar directa.Revisé los paneles solares y los cables y todo parecía estar en orden, pero aún así no funcionaron. Es decepcionante, ya que estábamos muy emocionados con este proyecto. No recomiendo este producto debido a esta experiencia.
