Cool Robot
This is a really well made robot and not hard for a 9yr old to build alone. The instructions to build are easy to follow. The first words of my daughter after turning it on and seeing it work were “wow this is cool, really cool”, I agree with her and it seems that the app has some good features as well. The kit contents are very well organized with lots of extra screws.

Highly recommend!
This was a great gift for our 10 year old! He enjoyed building it along with playing in the app to code and create for his robotic machine. Hours and hours of fun! Highly recommend!

Great first programmable robot
An easy first robot/programming experience. Built it with a group of children ages 7 to 14. Instructions clear, app clear and worked right away. Took about 3 hours total over 2 days from opening the box to having it move. Very worth the price.

Used and Damaged
I did not order a used product, but when I opened the box to wrap the gift for my son's birthday, I saw a fully opened box that had been carelessly (and ineffectively) taped back together with packing tape.

Bummer, maybe
UPDATE: Customer Support got back to me and are sending a new part. I have hope! The screws are tiny, and the pieces don't always fit together very well. I myself assembled it twice, and it still doesn't work. Reached out to customer support on Thames & Kosmos website, and have yet to hear back. Disappointing for sure.

Great gift. Definitely get it.
My 10 year old put this together himself in about 6-7 hours. He loves it. Definitely a great product.

Junior Robot
My son enjoys the robot. It was easy to build, though it needs parent supervision. It works with an app on his phone so he enjoys controlling it. I don't see the coding aspect though.

Fun for 7 year old.
My 7 year old grandson loved this! He was so excited and wanted to put it together as soon as he opened it. He and his dad assembled it and he played with it for hours. Good purchase.
