4M Green Science Solar Rover, DIY STEAM Powered Kids Science Kit, Boys & Girls Ages 5+

The Solar Rover works and works well. We gifted this to a friend that turned 6 as he is home schooled and his parents do a great job of explaining how things work. The gift was popular amongst the children as they all displayed curiosity.

Overall, kids think this rover is cool and it does teach them about solar energy in a fun manner. That said, the kids (grade 5) put this together themselves and were outside on a super sunny day and the rover did NOTHING! When we came out to inspect it, it turned out that the black and red wiring was not making any contact to the electrodes underneath the solar panel itself. We popped the panel out of the housing and saw that the + and - were flipped to the top of the rover when they should have been at the bottom. We popped it back in the right way, inserted the wires so they touched the electrodes of the solar panel and the rovers motor started spinning immediately. For those of you who also have the same problem, double check that the wiring is making contact with the correct part of the solar panel. :) Enjoy!

This was a Christmas present. It was fun to put together, but having read reviews that the solar panels did work, and then ours didn't work, I was disappointed. Fast forward 6 months--it works. I think the light was too dim in Utah at Christmas to make it work? We only tried it a couple days after Christmas and put it away. Maybe there was too much cloud cover? I can't remember. It works if there is enough sunlight.

So fun, great gift, not too big of a box, the instructions are good, great value

Bought as a gift for a 7 year-old niece, who loved it ( along with her 4 year old brother ). Was skeptical that the small PV panel would actually supply enough power to drive the kart along, but it did just fine. The kids loved seeing how they could stop and start the kart by putting it sun vs. shade. Instructions are adequate but could be confusing if one is not technically inclined. I would imagine that most kids would need some help assembling the components correctly but they can definitely still follow along and benefit from learning how gears, motors, electricity, and solar energy work.

Bought this for my daughter who likes to assemble stuff. It takes her only ten minutes to put it together. The parts look flimsy at first sight, but won't break if you're careful. My only concern is that the solar panel is not very sensitive to indoor light unless you just put it under strong incandescent light bulbs. Since it is most cloudy recently, my daughter has not had the chance to try it out in the sun yet. Besides, if not for the 5 buck discount, the price seems a little too expensive.

This was easy to assemble. Our 5yo granddaughter had minimal help.They work well in the sun (solar power of course) but we did try other light sources which didn't work. We did use the soda cans and had some wonderful races! Approved by Granny Camp

Easy to follow instructions, 20 minutes to build, and worked immediately on a not-so-sunny day. Kids were impressed and are now more into solar tech (the intended outcome!). Make sure to have a small Phillips head screwdriver for assembly. There are 5 small screws in total that we used (there was a 6th but didn't need to use it). Also, the wheels are a little hard to put on and may benefit from some cement to keep them on. The kit comes with a plastic 'body' as well if you're not interested in using an aluminum can. I didn't know that when I ordered, it was a nice add-in I thought.

Amazing gift for a 7 year old. The rover run wells in direct sunlight

I bought this for a 7 years-old boy birthday and he loved it! It's easy to build, but still very entertaining, it works well and is educative. I recommend buying this for kids. Totally worth it

Exelente regalo para un nino entusiasta y con ganas de aprender

Instructions were easy to follow on the first page, got tricky with the can. We are giving three stars because the red wiring broke, despite us being careful (in the first fifteen minutes) and right when we had figured the can part.

Lo compre para un adolescente de 12 años y lo armo muy rápido y funcionó a la perfección bajo el sol
