Kid loves it
This was a favorite Christmas gift for my 12-year-old. Unlike Lego sets he usually finishes in an hour or so, this occupied him for a couple days to build and he's been playing with it daily with the remote control. I love that it can be rebuilt into different models. It's sturdy and well made.

Fun and engaging robot kit for kids
I bought this as a Christmas present for my son, and we had a blast putting it together. The instructions were clear, and the robot worked as advertised once complete. The T-rex build is fun but a little unstable in its movement. The other robot options, however, are much more solid and work very well. Battery life is decent for the kind of playtime you’d expect, though I wish it didn’t use a proprietary charging port—it would be more convenient if it were standard. Overall, this is a great purchase for kids ages 5 and up who are interested in robots, Legos, or just enjoy building things. It’s engaging, educational, and entertaining all at once.

A lot of fun, but app isn't available on app stores
This is a lot of phone to build and play with. We opted not to use the app because it had to be downloaded from a website written in Chinese and side loaded rather than going through the app stores. Dropping one star for that. Otherwise great.
