My kids are having a blast with this, and it seems durable, so I'm going to give it 5 stars. If it weren't for them I'd give it a 3.It's a cool idea. I like that it can do zero radius turns, and that it's got spots to attach building blocks. We were able to use our name-brand ones on it - both the big-kid ones and the little kid ones. It moves forward and backward quickly. And the LEDs are nice. It's got two speeds.It's got some serious flaws though. The front wheels don't turn left/right, and steering it is not fun IMO. It slows down considerably when you try to turn, which makes it tough to manuever. The controls are all momentary switches, so there's no fine control. Just full-forward/backward/left/right. It's pretty light and tips over easily. There are two parts that pop out very easily - a rail and a roll bar. Every time my kids go to pick it up they remove one by accident.I would say it's worth it for younger kids who don't really play with RC vehicles often. Older kids or adults may be frustrated by the lack of control.
