My thermometer decided to start dying this morning when I woke up to take my temperature 😫 luckily was able to get a reading out of it after pressing the button a couple of times. I plan on finding a replacement battery and sticking to it for the rest of the cycle BUT I am thinking about getting a new one for next month. The one I have has no backlighting so it’s hard to see the reading. Have to turn my torch on. So do you guys have one that has a backlight , beeps quietly and read quickly ??? My current one takes forever 😑

I got it from amazon. Been using it since January . It’s the Mabis brand
