Review on Diagnostix 5110N ADC Otoscope/Ophthalmoscope Diagnostic Set, Pocket Size, Xenon Lamp 2.5V Hard Case Black by Gilbert Cokky

It's good except it doesn't do insufflation even though it has the port. I bought an insufflation bulb separately from Welch Allen which fits the port on the side of the otoscope fine except the otoscope is about as airtight as my ex-girlfriend, whom was a very promiscuous and flatulent woman. The lens on the otoscope rotates around and is not securely affixed so no matter how vigorously you try, air will not blow into the ear canal.
