Some six weeks ago, someone asked whether anyone had ordered one of these devices.
Also in the box was a little packet containing two perspex scoops, for digging out wax or doing permanent damage to your eardrum, or both, a cleaning cloth and a 3cm bit of sleeve which I they say is to protect the eardrum. There is also an instruction sheet.
The camera can be used with an Android phone, a PC with Windows or Mac (I have W10). With Windows, you have to download and install the software, which in my case took several attempts. It seemed to take ages to download, and crashed on a couple of occasions, as did extracting the zip file. I was about to give up when suddenly it all just happened. With a Mac system you don't need to download any software, apparently.
The only problem I have with it, is when I come to close the programme, it puts up an error message that it can't write the .INI file, and it will not close. I've given it full user rights (I think), so it shouldn't be that that's stopping it. As a work-around, I go through Task Manager to close it.
I can see the inside of my ear quite well, but have yet to understand what I'm seeing, whether it's wax or the eardrum. I need to examine both ears for comparison. I haven't attempted to scoop out any wax, nor shall I.
Lastly, be very careful when inserting anything into your ears, as you can easily damage your eardrum.
