We received this early June, and it no longer works. It stopped working for my son end of July.  It cannot differentiate forward from reverse. My 3 year old only used this around our back yard, so I am not sure what caused the issue.
I do not recommend. You can purchase better motorized toys for less and brands that stand by their products. 

Seats are pretty small, so although both our 5 and 3 year old fit per weight specs…the seats are too small for them to sit comfortably together. 
We have assembled other power-wheel toys for kids, and this was not the most complicated. Fairly easy to put together, about 30 min.

Our kids love this.
