We have twins who are about to turn 3. We bought two of these, one pink and one black for their birthday. Saying they love them is an understatement. Lol. I put both of them together myself. Wasnt difficult really. However there was one nut missing for the back tire on both of them and I ended up having to run to the hardware store to grab a pack of em. It looked like they were laying in there freely and the tape got cut on the ends on the boxes which probably led to them falling out. Theyre super sturdy tho and the controllers are awesome. Helps me teach them to drive while they sit in them. Plus my 8 yr old gets a kick out of racing them. Lol all in all it was well worth it!
