I have used many different brands of otoscopes for the last 20 years. I’m retired now but I thought this would be a neat new tool. Setup was easy although I had to shoot a picture of the instructions and blow them up to be able to read them. Way too small to read with old eyes. Setup was easy. I used my iPad to download the program and the unit found my router rather quickly. It did say it could not find the internet but then the communication was between the unit and my iPad. Internet not needed. The screen size, even on my iPad, is small. Very disappointing. The camera has to be 2 to 3 millimeters close to what you want to view so a complete view of the ear canal, from opening to eardrum, is impossible. Bottom line this is really a toy, a fun toy, that can be used in several different ways. As the old saying goes, “you get what you pay for”.
