That fancy coolant testing strip I swore was a gimmick
Been using the old refractometer for years to check coolant freeze point. One of the guys brought in these test strips from Napa for like 15 bucks for a bottle of 50. I figured they'd be garbage but tried them on a 6.7 Powerstroke last Tuesday. Strips matched my refractometer reading exactly on three different trucks. Now I keep a bottle in my box for quick checks on fleet trucks, still use the refractometer for my own builds though. Anybody else found a tool they thought was junk that actually works?

Grabbed a set of those cheap digital calipers from Harbor Freight (like 12 bucks maybe) thinking theyd be total junk but theyve been dead nuts on for years now. Still grab my Starrett for anything critical but for quick measurements they honestly havent let me down.
