I accidentally ordered this one, and immediately returned it. It's not that it's fundamentally a bad product, but I intended on getting the LED otoscope. This one has an incandescent bulb, which not only drains batteries 10 times faster than an LED, but has a lifetime on the order of hours.
For the technically minded, the LED otoscope appears to have a DC-DC boost converter, so it should still work even when the batteries are very low. Get more detail about The Original Doctor Mom Otoscope, otoscopes.
