Review title: Have a very NOISY Christmas . . .
Product review: I am writing this review while this toy operates about three feet away. It is so loud that I can't hear my children's (5 & 7) voices or the TV on the other side. I'd say it's about the same decibel level as a sheet metal factory. There is also a safety factor. When the cars come off the track, as they eventually do, they are going fast enough to cause an injury. My children just stopped playing with this toy after about 15 minutes (thankfully).
