checking disc brakes

I got the Walmart endoscope working.

However. It's a tad thinner and flimsy.
It'll need securement on a rod of some type. Otherwise. You're basically playing with a string. Be hard to run it through the rims and point it where you need it. 6 lights and resolution isn't the best. Don't expect to get too close to the patient.

The Amazon arrived today. It's stiffer (more like a snake) so it won't need a rod. And can be bent to the desired angle. Should be no problem running it through the rims. Much better resolution and 8 lights.

Amazon uses app called usee. It's a small square with phone straight up. Full screen with phone on the side. Clarity is great either way.

Walmart I found 4 apps to use. Only one will do full screen. Color endoscope. However. The bigger the pic. The less clarity.

Both cameras work with windows 11. Ulysses is the app. I don't have a 7, 8, or 10 machine to test. Both cams had good clarity on the laptop. Amazon was better though.

Walmart will more then likely be going back. I can't see a flimsy camera being very handy.

Walmart was $16 after shipping and tax. Amazon was $40 for overnight. $4 less if I wanted to wait 6 days.

Now for the test run.
