I’ve had this thermometer for quire a few years now, works well for the most part, but sometimes I feel like it has issues and the more you use it the more the accuracy declines. Meaning, if I take my temperature back to back it just doesn’t seem accurate. Sometimes I check with an old-school thermometer afterwards just to be sure. I don’t know if it’s because I’ve had it so long because It didn’t really do this that much in the beginning, but I would purchase it again. Battery life last pretty long. ￼ I would highly recommend it.
