Ultra 100 Pack - Celsius - Single-Use Thermometer, Individually Wrapped - Superior Accuracy and The Ultimate in Infection Control - Extended 1-Min Signal Retention

Hard to use

Not accurate - bought a drug store brand digital thermometer which works well.

Doesn’t work. Horrible. Tempadots are much better.

I will admit that it was an error on my part, thinking that this product would give temperatures in Celsius and Fahrenheit. Pat of my confusion is one picture they have in the product details which shows a reading for both Celsius and Fahrenheit. Since this product only gives readings in Celsius, they should remove or update that picture. (There is another picture in the larger product information section, showing only the Fahrenheit version of these thermometers. Serves only to confuse customers.) But, that does not detract from the effectiveness of these disposable thermometers. Basically, 37.2 ° C = 98.6° F. And the formula to convert from Celsius to Fahrenheit is F= 1.8C +32. Not an easy computation to do in the head, especially when trying to deal with someone that may have a fever. In a rush, I know that over 37.2 ° C indicates fever territory. And, to make life easier, I printed out a 'cheat sheet' conversion chart and inserted it into the box. I found the dots method to be a bit counter-intuitive, but once you understand the system, you can readily determine the temperature. I compared the reading of one strip to a conventional digital thermometer, which I actually set to ° C. The strip gave the same temperature reading. So, for a one strip sample, the result was excellent. The product does match up to the description and operation noted in the product details. Hopefully circumstances don't persist wherein the need for temporary, disposable thermometers is necesseary. Credible disposable thermometers that deliver same temperature as a digital unit. I do wish the product had ° F readings, but I see that it is a separate product. I do place some of the fault on the company's manner of presenting this product, creating the confusion regarding Fahrenheit readings. Based on these considerations, this product receives a 4.25 star rating. Recommendation? Buy it if you want Celsius readings, otherwise search out a Fahrenheit based product.

Many people are using a more rapid way of gauging their body temperature by using a no-contact digital thermometer. I do have one of those, but at times they can be inaccurate. This I know because the one in my physician’s office briefly malfunctioned and read my temperature at 94° F. I thought I’d give the NexTemp Ultra a try to see just how accurate they are. Normal temperatures do fluctuate, so before beginning a daily reading, you should know your usual reading. I tend to be around 97° + F so knew where I should fall on this scale. There are directions in the box in a wide variety of languages, including English. If you need to gauge your temperature daily, this are perfect. One can use these disposable thermometers either orally or in an axillary manner. I’m not a physician, but I do value the advice of the Mayo Clinic. They state that “The average body temperature is 98.6 F (37 C). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. Your body temperature can vary depending on how active you are or the time of day. Generally, older people have lower body temperatures than younger people have.” According to the Mayo Clinic the following thermometer readings generally indicate a fever: • Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher • Oral temperature of 100 F (37.8 C) or higher • Armpit temperature of 99 F (37.2 C) or higher I removed one of the thermometers from the wrapper and put it under my tongue as directed. I left it there for a full minute. After that time, it was quite easy to see that my temperature was in a normal range. My reading was 36.6° C or 97.88° F, exactly where it should be. The little green dots on the face of the thermometer disappear, if you can call it that. They darkened and the last one tells me my temperature. Each dot is a tenth of a degree so I could easily see that next to the 36.5 row there was one darkened dot (the rest were green). At first glance it looks confusing, but isn’t. You do need good vision as the dots are small, but I was prepared with my readers. Very accurate disposable digital thermometers I’d very highly recommend. These are very accurate and easy to use. If you don’t “do” Celsius, simply take a pass. For those who need to have accurate readings, the price is equitable.
