In another thread, @miket asked me what kind otoscope I bought to self-examine my ears for the presence of wax. Rather than go off-topic on that thread, I decided to start a new thread. This is what I use:
I have a susceptibility to wax buildup. The first time I went to Costco, the lady who examined my ears told me wax needed to be cleaned out of my ears. Then I went to CVS walk-in clinic and the nurse declared my case to be beyond her skill. “Use eardrops for a week and come back.” Yeah. I decided I should figure out a method to take care of it myself. I’ve used this device to check my ears so that I know when I need to clean them. I’ve used both my Pixel 2 phone and my laptop to view the image produced by the scope. Then I use drops and an ear wash system, and this approach works fine.
The device comes with a bunch of tools for removing wax. I do not use any of these tools to remove wax, and I do not recommend that anyone use them. Most of the digital devices sold on Amazon come with the little tools. I use peroxide drops or a water/peroxide mixture in the ear wash system, and only that.
There are dozens of similar devices on Amazon. I’ve seen some cheaper devices, but they had bad reviews. I did not check every single device available on Amazon though. And prices change so I would not be surprised if there’s something of comparable quality but cheaper to be found.
Also, YMMV. The devices available at that price point usually have a fixed focal point, so you get a blurry image unless you position the device at the right distance from what you are trying to see. Judging by the reviews, that’s a problem for some people. I also saw a $300 device that does a whole bunch of amazing things and most likely has auto-focus but that’s more than I want to pay.
I also have a non-digital otoscope (the same kind you’d see in most doctor’s examination rooms) but I’m not physiologically equipped to be able to see through it while it is pointed at my eardrum. I have to ask my wife for help if I want to use that one, and she obliges, but that gets old.
