        Precise, Fast, Needs Improvement

        I provided this feedback to the company. We got 2 of these in 2021 as they were highly recommended. They were very useful for monitoring accurate temperature for serious medical conditions. One broke recently (my fault) and the company replaced it. In those 2 and a half years I have more hand and finger arthritis and vision changes. Pushing the "button" is very hard, almost impossible now. Can't get it on. Getting the cap off to change a battery too hard. Seeing results sometimes hard. Other than that, this is a very good and fast product. Would love a larger version and "button" more responsive. I can confirm that Customer Service is excellent and that matters a lot.

        Yes, it’s fast and accurate.

        I compared accuracy with an older digital model and the “gold standard” mercury stick type, consisting of several trials over several days. There were no significant differences in readings among the three. The iProven was within the claimed + or - o.2 degrees F the vast majority of the time. These results are corroborated by a formal scientific study generally comparing digital vs mercury types I found by goggling.
        And, yes, accurate readings are available in about 10 sec as claimed.
        A final point: the clear plastic cover on the screen and button should be removed, as doing so does cut down on some of the glare in seeing the readings. This is not referenced in the accompanying instructions, but the Walgreen branded version does so.
        Even at that, however, the button is still hard to push. Why has iProven not addressed this issue?

        Great thermometer great price

        I bought the 2 new ones because my son loved it for axillary temps for my baby granddaughter

        It works just fine!

        I've used it a couple of times, and it seems to be working just fine. A good price and a top rating are the reasons that I bought it.
