My braun ear thermometer died for no reason. Changed the batteries but it seems it's off by .5 degrees. Anyway used the free one from Wellcome (Kuhn Rikon) tolerable, off by .1-.3 degrees. Safety first digital thermometer is good for non squirming babies. But I found a really good one. Beurer Pacifier Thermometer for babies and the forehead thermometer for kids/adults. They are accurate and very easy to use. Finally, I also bought the old fashioned mercurial thermometers. I got the ones from Watson but found it too difficult to use or rather easy to make a mistake. Found another mercurial at the Chinese Dept Store. So far so good.
