I’m getting old, and seeing the dial gauges when I leave my readers inside is getting harder everyday! I’ve had this old Reb-Co gauge for over 20 years, and it works like a champ! Moved onto a digital backlit gauge this week, and I’m happy with it so far. I can see it without my readers too! Hopefully it’s lasts 20+ years too! They were 25% off on the big A store.
