Crummy junk. National Geo should be ashamed to have its name on it.
JUNK. Two problems right away. First, the digital setting for the run time (days) keeps re-setting to zero. Second, the wheel connected to the motor that drives the belt broke in the first 5 seconds!!! See the picture. It is a crummy little plastic wheel - there is no way it will last. It is connected in the center to metal rod from the motor, and will wear out for sure. This wheel should be metal, not plastic. This thing is NOT built to last. Clearly the electronic part of it is screwy too. I expected more for my $119.00.
