That said, my <$10 Harbor Freight tire inflator / gauge with 3" dial, which connects to my $80 Harbor Freight air compressor, has been serving me well for about two years now. I don't know if it's accurate, as I don't have anything to calibrate it against. However, it "feels" accurate. If nothing else, at least my tire pressure is consistent.

I got refunds on all of them...so far. The Tekton lost the gasket that fits the valve stem...2xs...just barely found it last time...glued it in...so it might last now.
My old Victor felt accurate and was consistently...LOW. The gauges on air tanks and compressors are ALWAYS off?
The BIG PROBLEM is that if you are overinflating by say 4-6 PSI AND your gauge reads low by 6 PSI...and you are trying to SENSE roadholding/ride and so forth using a false reading....6 lbs over...you are fooked.
Many reviewers on Amazon don't like the digital gauges due to low batteries and unreliability in cold weather, etc.
My solution is to keep two dial gauges that mostly agree...and verify them at a tire store...I guess. Once I think I've established an accurate pressure...I might buy another Victor since they are only $5...drop it ..buy another?
This MIGHT be a decent digital gauge?
