Great Gof
Great Gift for my niece. She loved the challenge of putting it together and it kept her busy playing for hours

Highly recommend for mommy/daddy & me project!
This robot kit is awesome. I bought it to work together with my fairly advanced 3 year old. It’s very easy to assemble - it is very “Lego-esque” in the instructions, shapes and piece intersections. If your child is Lego-savvy, they will probably be able to complete this project on their own. We were able to get it done in 3-4 hours total. My daughter was able to click a lot of the pieces together and help count and find the pieces herself. The final product (Model A) is an adorable robot to at moves around very well via the remote and makes some pretty entertaining and emotional sounds. My daughter loves playing with it and can use remote fairly well on her own - she’s been chasing the cats around our living room and kitchen with it for over an hour now! Defiantly my favorite art/craft/project purchase in months! Highly recommend.

Sillbird Robot-building kit is a winner!
Ten year-old grandson built it in 4 hours or so. Very detailed pictorial instructions, colored pieces matched instruction diagrams, and components are very precisely manufactured. Remote control worked well, and the tracked robot moved quickly and entertained with eye motion, and funny noises.

Pretty difficult to put together
We got this STEM robot building kit for my son, who loves building with LEGOs, but it didn't quite live up to expectations. While the concept is great, the pieces are not very durable—several broke easily during assembly, which was frustrating. The instructions were also a bit confusing, making it harder to put together than anticipated. My son enjoyed the challenge of building, but we were both disappointed by the quality of the materials. Overall, it's a fun kit, but it could definitely use some improvements in durability and ease of use."

great toy
Great gift for children who are into legos and robots. The materials were acceptable for children in 1st grade on up. The toy can be made into different toys, but only if it interlock with legos would have been fun.

Excellent product and excellent company.
This is a wonderful product that kept my grandson busy for hours with a perfect result. And it works just as advertised. The beauty of it is that you can take the robot apart and build different models. In addition this company gave us excellent service. Because of his very inquisitive mind, my grandson took the control box apart and broke it. The company didn't hesitate to send us a new control box for free that we received within 2 weeks to my relief and that of my grandson.

One of my Sons Favorite Christmas Present
One of my Sons Favorite Christmas Presents of the year. STEM is absolutely his favorite part of school & being able to share the experience with him at home has been priceless. Together we have built 3 of the projects with the robot being his favorite.

Many pieces but my grandson had together in no time?
Gave this to me grandson for Christmas he loved it especially when he had to put it together even though he was a little under the age requirements on the box.

Loud and fun!
My 15 year old wanted this kit, so it was a Christmas gift. He knew it was geared to a bit younger audience than him but he still had fun putting it together. He has only done the main robot so far. There were a few parts that required some help getting the pieces into the slots because they were a bit tight, but other than that it was a good build. The only part that *I* don’t like is how loud it is - both the motor and the noise the robot makes. Oof! It’s good to see him having fun with something that’s not a screen though, so I’ll manage!
