Good post bro! There's the proof right there!All this are cheap, calibrated(!) and in the same R/O water. Look at the numbers and think again before buying a cheap one.
$7
That is how much a drip tester costs.
I used drip testers to calibrate my ph pens, expensive and cheap. They all eventually failed.
The drip tester has never failed me. It never has to be calibrated.
I'm sure some expensive ph tester works well and lasts years, but I am done throwing money away looking for that one.

You take some of the water to be tested in the little plastic jar, put in a few drops and shake it a bit.
You can tell the ph by the color. You can be pretty accurate if you can see colors well.
