I have one and infrared thermometer and a few other things. I have a covid kit I travel with for just in case. Put it all together back in February 2020 when the crap starting hitting the fan, along with a list of things I need to do (if they work or not). So far, never got covid (fingers crossed).
*my oximeter reads 92-95 routinely because I'm in a high elevation. But, when I travel to a town near a beach it's always very high. So, if mine goes to 90 or lower that's my warning level.
