Bought a cheap moisture meter on Amazon for $12 and it saved my drywall patch job

I was patching a water stain on my bathroom ceiling in my 1950s bungalow and kept getting bubbles in the mud. Turned out the old leak was still damp behind the paint. The meter showed 18% moisture in that spot versus 6% everywhere else. Do you trust those cheap moisture meters or are they just a gimmick that gets people chasing phantom problems?

That 18% vs 6% difference is exactly why I keep one in my toolbox, saved me from mudding over a hidden leak in my own bathroom last year.

That 18% number would've saved me a ton of rework last month.
