Fun build
Easy assembly. Loads of fun.

Easily put together
After putting together a few toys and robots for my kids, I’m always nervous about putting one together. But this one had great instructions and it took me about 30 minutes total. I put it together without my kid because they’re quite young but I think a kid 7 years or older could handle it. It requires 5 AA batteries. It has so many modes, doesn’t require you to code to make it run, but it also has a coding mode where you can instruct it to do a set of tasks. My kids were also delighted that it had a “fart” button, lol. Overall, a great quality robot and brings plenty of fun and learning about coding.

Fun to build
This is designed for older children but younger children can also enjoy it if they have a grown up helping. More fun to build than to play with. The programming is just giving the remote a list of steps to follow. The motors are not very durable.

Thrilled with this
This was just the stem activity we were looking for. My then ten year old had no problem assembling this, and has enjoyed playing with it and making the modifications to allow it to do different functions. It's one he will get out every so often, even a year later.

Son loves it
Got this for my 7y we built it together. I had to help him with the building instructions as some parts where hard for him to understand how it went together. Only problem he has was snapping the pieces together but his finger strength is a problem for him. Once built he loves playing with it ! He loves chasing people and making it fart. Only problem is it can be front heavy and fall forward sometimes Overall happy we got it

GREAT purchase
My 5yr old at the last minute said he wanted a dino that we could build together, then added “thats a robot”. I was a little skeptical at first but was pleasantly surprised. Parts fit well. Easy to assemble with clear instructions. Be was engaged for about 25 minutes and helped build the legs and installed the motor. I finished assembly in another 20-25 min. He really enjoys it. Whoever thought to out a fart noise on the remote is a genius he spent 30 min just making it fart and laughing his head off.

Quality materials, clear instructions
I bought this for my 6 year old son. He and I had fun building it together. He mostly just needed help making sure the wiring was ok (it’s simple and has easy to follow instructions throughout). It works well and he loves using it to battle his other remote control toys, so it’s sturdy! Great toy overall, no complaints so far!

Dino kit
Kids really enjoyed this. Takes couple hour to assemble as adult so prepare for that. Instructions are easy to follow. Control has lots of options to explore. The finished product does not move very quickly but can be maneuvered around, under, through and in reverse too. The kids enjoy the noises (soft farting sound) to add. Recommend as fun gift. Good value for the cost and interest.
