When I inserted the first sensor on Saturday, I thought it might give me a little trouble. It'd been through a lot in the last months (traveling around in my "everyday" case and moving from fridge to backpack to suitcase multiple times). It looked old, it looked like it wouldn't work. But I gave it a shot anyway.
And my suspicions were confirmed. It gave me two error messages before showing me a steady level in the 50's when I was perfectly okay. Instead of messing with a crazy sensor and wondering about its accuracy for days, I changed it out. I had an entire new box of them anyway and I don't use them often enough to be upset on throwing one out.
