learned thanks to my dog that dog hair gets caught in my ears. That's great. Amazing image quality and the ability to save to an SD card. Since it's wired, there are no latency or connectivity issues. However, due to some witchcraft, you can't use it on your PC or with your smartphone, even though it uses a USB-C connection. OH WELL. I just can't get over how awesome this thing is and absurd for $80. I would 100% recommend it especially if like me you have suffered from ear problems in the past. I had tubes in my ears due to drainage issues and chronic ear infections. I don't get ear infections as often as an adult, but if I leave water in it after a shower, my ears tell me it was a mistake. So... a valuable tool at an amazing price. I've tried the ear cleaning attachments, but not only can I get by with the inverted controls on the x-axis, but also on the y-axis. This can possibly be solved by simply turning the machine upside down. I don't know why I thought of this simple solution just now. What ever. Not important. The main function is that it is a scope. The screen is dense enough that images look nice and clear. It's just amazing that you can buy something of this quality for $80.
