So I will preface this by stating I am a Licensed Audiologist in California and have been looking for a good video otoscope to use, I have used ones from JedMed and the Firefly and both work ok, but this has much better functionality, better image quality, easier interface and much more feature rich. The JedMed offered only automatic lighting adjustment and later on manual adjustment but it constantly had issues, the images were blurry, it cost over $500 Etc. this device and capture video with sound, sound is not really vital but if you want to dictate what your seeing as you see it, that’s possible, you can adjust time stamps, label videos-pictures, turn the light completely off or anything in between, has an external micro SD card for storage, amazing battery life, I have to say the only downside what so ever is that it’s fixed focus so in other words you can’t adjust the focus and it’s completely determined by depth of the scope, this is ok for most of my patients but say children has smaller and shorter canals which can make it tricky to get a good image in focus. Overall though this is absolutely fantastic and well worth the price. I would definitely buy this again in a heart beat versus paying $500+ for something with less features
