Query: DO NOT BUY!!!!!!

I purchased one of these minimotos as a birthday gift for my son and he enjoyed it so much that I went back and bought another one for my other son. After 3 months they BOTH stopped working. After purchasing a battery, troubleshooting on the phone for hours, and becoming very frustrated, I was told that I would have to replace the MOTORS MYSELF before I could get any kind of reimbursement. THIS IS A JOKE - I had to saw off a screw to even get to the battery!!! I even purchased two Toys R Us Protection Plans for $50.00 - all together a HUGE waste of $$ - 3 months of use for $199.00 is not worth it!!!!!!!!!!
