So I would like to start off by saying that I am a licensed audiologist in California and have been looking for a good video otoscope. I've used one from JedMed and the Firefly and they both work fine, but this one has much better functionality and image quality, simpler user interface and a lot more features. The JedMed only offered automatic lighting adjustment and later manual adjustment, but there were constant problems, images were blurry, it cost over $500, etc. This device and recording videos with sound, sound doesn't really matter, but if you want to dictate what you want The way you see it, that's possible, you can customize timestamps, annotate videos and pictures, turn off the lights completely or anything in between, has an external micro SD card for storage, amazing battery life, I have to say the only downside whatever is because it is a fixed focus ie you cannot adjust the focus and it is entirely determined by the depth of the endoscope. This is fine for most of my patients, but let's say children always have smaller canals, which can make it difficult to get a good image in focus. Overall, however, it's absolutely fantastic and well worth the price. I would definitely buy it again in a heartbeat rather than paying over $500 for something with fewer features
