Review on 📏 Dwyer 475 6 FM Digital Handheld Manometer by Darion Wooten

I have a 3 Series 475 Mark III. Two of them broke right out of the box. Both of these problems stemmed from the buttons not being properly aligned with the main switches. It's not like they were damaged in transit - they were broken. If they work, they're fine - simple but good. It's hard to find anyone other than Dwyer making a digital pressure gauge designed to work with combustible gases. Dwyer needs to give his Quality Control department a kick in the butt.
