Right out of the box, this toy was awesome. Assembly was extremely easy, and my husband most appreciated the tools that came with it. The battery was supposed to charge for around 14 hours, but it was done after about 8. We kept it on the charger, though, for the full time. All sounds work, with a provided volume knob which I was happy to see. All the lights work. My son is thrilled with it. It's powerful enough to navigate our dirt and rock, very uneven back yard. We played with it for about 45 minutes outside, granted with a lot of start and stopping. It was still going when we parked it and went in for lunch.
The only downside, that I could find, was the fact that the passenger door sticks and is a little hard to open. Other than that, it's all great. Very pleasantly surprised. I would have to recommend it to anyone with larger yard space.
