Query: Very loud, battery hog

I think most battery operated toys benefit from having volume control. This is an extremely loud toy when it beeps. Also, it's easy for a kid to leave either a car or remote control on and drain the batteries completely (my husband even did it once) because there's no automatic shut-off. After that happened a couple of times, we just shelved it for a while. (Each remote takes 2 AAA batteries and the cars each take 3 AAA batteries, so yeah, 10 AAA batteries!) Lastly, if you own a pet, the wheels are small and can get seriously tangled up if you haven't just swept your floors; you have to take the whole thing apart to clean them out. On the upside, the kids do love it, a definite attention grabber.
