I believe these cheaper devices are not very accurate ie accuracy range of 20% which is a fairly wide window. I’ve also heard there are many things that can impact your glucose even with the same meal like time of day, exercise, stress, sleep, etc. So if you actually want to find the patterns you’d need the expensive CGM over many months.

Is that true? I have no perspective but it's relied on by diabetics and if since they can't regulate it themselves, if the readings are off and they gave themselves insulin, they would know it is wrong. Maybe the OTC ones is different than the diabetic one but I didn't think so

Most T1Ds I know use a CGM now as they are much more accurate than they used to be. But they are expensive so insurance generally covers for T1D but not T2D. You can always double check with a finger stick though as that uses blood instead of interstitial fluid. My friend uses a Tslim which uses a CGM to adjust her insulin automatically.
