Good gauge. Worked flawlessly for years until display stopped coming on. Almost bought another brand that has replaceable battery tray. Decided to think outside the box and took to this Devilbiss gauge with a dremel cutting disc.Sure enough, perfectly accessible CR 2032 battery inside.Not the best technique if you are concerned about keeping the unit certified gas proof. But a new battery and piece of painters tape to put it back together works fine for me.
