Very easy to use. Before you actually enter the ear it's best to look at the picture on your device and get the camera oriented right side up, otherwise an upside down image makes it hard to adjust/maneuver/navigate. Also Camera becomes warm/hot fairly quickly so short duration use is better, I wouldn't reccomend leaving it plugged in for any length of time. I love how portable and easy this is to use, all surfaces including the cord tie are easy to clean/disinfect. Went straight into my nursing bag! My ear had been irritating me a bit so after this arrived I took a look and found a loose hair near my ear drum, by using the camera I could tell where in my ear canal it was sitting and then gently used a q-tip to bring it out, yay! Posted before and after. The price seems great and I'd totally recommend this to anyone!
