This thermometer works fine, but on first use, I had to try several times to get an accurate reading on my 11 yo. I could feel with my hand that he had a slight fever but was getting readings that were actually below normal. I also had some inconsistent readings from one ear to the other or from subsequent readings from the same ear, and I got unusually low readings (95) on my husband. It may just take some practice in pulling the ear back properly, since after several tries I was getting more consistent readings. So though it does take only 1 second to get a reading, I felt I had to take several readings to be sure I was getting an accurate result. On the upside, it only takes 12 seconds for the thermometer to be ready to take a new reading.
One annoyance with the product is that its default setting is Celsius. You can change it easily to Fahrenheit by holding down the "on" button for 3 seconds, but you have to do it *every stinkin' time*! You cannot make Fahrenheit the default. Also, if you forget to change it and get a Celsius result, you can hold the "on" button for 3 seconds and it will convert your reading. It's not a big enough issue to return the product, but had the product description mentioned this, I likely would have chosen a different thermometer.
Oh, and be aware that the instructions are written in "Engrish." And no, that's not a typo. I.e., no one who speaks English as a first language reviewed the instructions before they were printed. They are mostly decipherable, though mildly amusing.
One instruction I have a problem with is this: "Calibration frequency: two years, please done [sic] it by local Supervision Bureau." OK, so I get that the thing needs to be recalibrated every two years, but what the heck is a "local Supervision Bureau"? Who does this? More likely I'll just need to buy a new one in two years.
