The manufacturer notes that the motor will run for years, no doubt aided by an automatic shutoff timer.
It's not just educational, either -- the National Geographic Professional Rock Tumbler is ideal for putting together homemade jewelry, with included fastenings for creative hands to use once the rocks are polished.
Customer reviews are positive, too, with many praising its ability to polish rocks -- as long as you have the patience for it. Some have also noted the noise that the machine makes, so buyer beware if you're rock tumbling in the house, even with the noise-reducing barrel.
