Query: Hate it!

My Braun thermoscan has given me nothing but trouble.Yes this ear thermometer is easy to use. You just have to stick it into the canal correctly. Not hard. What I don't like is you can stick it in the same ear, the same way, 6 different times and get very different readings.Everytime I have gone to use my thermometer, the battery would be dead. You have to use the special medical circular batteries, so of course I would never have any handy. Then I got smart and started stocking up on the batteries. They are expensive. And everytime I would use it I'd have to put in a fresh new battery.This also needs the disposable ear covers in order for it to work. Yes there is a trick to getting around it but then your thermometer isn't sanitary. Finding the covers was sometimes easy and sometimes impossible.I have just never been happy with it. Yes it's easier than the oral... But I found one even better. Try the Temporal Artery Thermometer. You can use that one on a sleeping child!
