Changed the batteries, yes. Technically it works, but the readout is so faint now you can't even make it out in the dark. I don't see anyway to adjust it, but thought I'd ask before getting a new one.

I got one at Walmart, Equate brand. Want to say about $35, with a nice case. Get's used a lot. We recently drove from sea level to 9'600 ft in likr 2 hours. My o2 dropped to 75, even with boost oxygen could only get 86 so we headed down after like 20 min looking at the aspens change color. About 7,000 ft I came back to 95. But I was flirting with altitude sickness had we stayed much longer. Glad I brought the oxymeter!

We bought one from Amazon back in March while they were still cheap and easy to find. We use it when we are feeling ill to make sure our oxygen levels are ok.
Mine's been working for many years. Long enough to experiment with it.
Run 100 yard dash with it on. See how you recover. (Ok, jog then!)
Wear it while riding a motorcycle. (In case you don't know, motorcycling can "ram feed" oxygen to you.)
Use it while hiking. (More for BPM.)
Lots of ways to use one.
Develop a base line, and look for changes to that baseline.
It's a tool, use it.
