Nice compact size pocket otoscope with the same excellent function as our Third Generation Dr Mom LED Otoscope only better. It uses a larger optical quality glass lens. Handle and switch is built from a nice quality heavy grade aircraft aluminum metal. The amount of light produced for visualization inside the ear and the clarity of vision is second to none on this otoscope. I have been an ER Physician for 25 years and have used many different otoscopes throughout my career. In my honest opinion I can see the tympanic membrane as clear with this otoscope as I can with Welch Allyn models costing much more. We offer a no risk 60 day no questions asked money back guarantee. Give it a try I think you will be very impressed with what you get for not much more money than the cost of a simple Welch Allyn Halogen bulb. Not to mention this otoscope uses an LED module on circuit board with a DC/DC boost converter and voltage regulation and will probably last a lifetime without ever needing a bulb replacement. Batteries will also last and last sometimes up to 6 months to a year being reported by our customers. If you are a medical person and have used otoscopes in the past and have realistic expectations on what you are normally able to see inside the ear you will be especially impressed with this otoscope I guarantee.Imported
