VANLINNYRobot Kit,Science Projects for Kids Ages 8-12, 2 in1 Electronic Robotic Arm for Boys & Girls to Learn Programming/Techology,Educational Toy Building Kits for Beginners,Xmas Birthday Gift.

My 10 yo daughter and I built this after she received it for christmas. Good instructions, but a technical build for a kid. Lots of controls to get the robot arm right where you want it, it’s also pretty fast and fun to just cruise around with it.We had an issue with one of the motors - there are 6 total, and they sent a replacement out quickly at no cost. great toy and built to last.

The toy that we had got has an issue with a missing part.There is this part with Code QD-A and QD-B, there is supposed to be 2 pieces of QD-A and 2 pieces of QD-B but in the box we have 4 pieces of QD -A and QD -B is missing all together.

The gear for the arm is not hefty enough for average usage..Overall a great learning kit! Price in ballpark..

We bought robot arm for a skit we did for a YouTube video and it worked great. However, since then, we have been unable to stop playing with the thing. It's gotten to the point that it's distracting everyone from work. We set up obstacle courses and all kinds of "tests" for it. We also tease the office cat. The battles between Cat and Robot have become legendary.We're not the smartest folks on the planet so it took us longer than normal to assemble the robot. I estimate about 3 hours of refusing to follow the directions and just slapping parts together until we finally got it right. I'm sure a normal person, using the directions, could prolly assemble this thing in a 1/2 hr or less. The grabber arm is strong enough to hold a small plastic sword and frequently withstands full powered frontal assaults from Office Cat.

The directions are a little hard to follow for English speakers, but the pictures are pretty good, and the parts are well labeled and packaged.It's super fun to drive, and surprisingly fast for a single 18650 battery. It has pretty good lift and grip on the robotic arm.The drive noises are super annoying, but really fun when chasing my cats.

Broke a kid’s heart. Bought as a gift and after a full day spent assembling this toy with my 7 year old, the axle that connects the heavy body with the wheels broke within literally 1 minute of driving. The break is irreversible. Why would you have a solid metal body and active fast wheels if you are going to connect them with a flimsy white plastic that cannot handle the weight? My kid cried for hours and knew there was no way a replacement with the same architecture would last longer, so we got a refund instead. Good thing we assembled this within days of buying - so many hours wasted.

Sorry to say, some of the key parts needed to put this together were not included in the box. I've returned the item, not sure if I should trust another.

It's a very neat concept but aftermy son and I put it together we noticed that the front left motor is defective. I am trying to contact the vendor to get a replacement part. Amazon suggests sending back the entire product but that seems unnecessary.Once the vendor responds, I'll update my review.
