VicksRapidRead Digital Thermometer, Temperature Readings in 2 Seconds, Use as Oral Thermometer, Baby Rectal Thermometer or Under The Arm, Water Resistant

There is a small mini-booklet in the package that explains how to set up the thermometer (arm, mouth, or groin) for the first time. Once this is setup, the thermometer will go through a 10 second self check, zero out the display, and within two seconds this thermometer gives wicked fast, wicked accurate results with an easy to interpret stoplight color lit screen (green, yellow, red). I don't know why anyone who gets one would buy anything else.

Disappointed with this thermometer. Upon arrival, it did not work with the battery it came with. I changed the battery and it turned on, but I’m not convinced it worked correctly. Every temperature I took, it registered as 100.2. I used it maybe 5 times before it stopped working completely. It now gives an error message, tries to read a temp, then gives lines on the screen like it can’t read a temp. I was excited to use this due to being able to read a quick temp. Will be going back to other slower thermometers now :(

Our go-to thermometer. This was the second I purchased in case we lost one! Love how fast it is and easy to use

Our go to thermometer for our littles. Easy to use and quick response time on reading

Very good so far I’ve only had it for a day though. I work in vetmed and love the rectal vs underarm modes. The only thing is the battery that it came with is dead. Luckily came with an extra but might of well have only given me one if they weren’t both going to work :(

All I want to know is what's the temperature. What difference does it make where the measurement is taken? This device is more complicated than it needs to be and the setup process is difficult, because the setup responses listed on the lengthy instructions are not the responses I got. It was impossible to set up to get the first reading. I assume the device was defective and I returned it.

The battery was dead on arrival, but it works well after we replaced it. I primarily wanted this for rectal temp and you have to press the on button then the "route" button three times with a pause between the before you get to the rectal option, which is definitely not convenient when you have a sick and squirmy baby you need an accurate temp on. The accuracy is also debatable, when I'm able to get baby to stay still, I take the temp 3 times, and often the second temp is a full degree less than the 1st and 3rd. I do appreciate the flexible tip though.
