This doesn’t reflect the actual battery level and doesn’t mean the battery is low or running out.

    Do not buy this it is horrible

    This thermometer is absolutely horrible. The flex tip makes it impossible to get an accurate reading as you have to hold it in place closest to the tip in order for it to read appropriately. It may be best to use as a rectal thermometer, however, trying to read it as an axillary is definitely virtually impossible

    Inaccurate readings (IF it works)

    This thermometer was extremely unreliable. It gives out different readings each time (variance of 3 degrees!!) IF it even works. Sometimes it just gives dashed lines and glitches out. Waste of money and just more plastic garbage.

    This is the most inconsistent thermometer. I read all instructions and regardless of waiting between readings and staying stone cold still, the readings would be dramatically different. The thermometer would slow its climb around one number then suddenly jump 2+ degrees to the next number. Compared it to my old thermometer and it is 1.5 degrees higher but at least the old one stays consistent. Would not recommend.

    Do not waste your money - not accurate

    Terrible! Does not accurately read your temp. It gave a different temp reading: 99.8 then 2 mins later, 97.8. It said I had a temp of 100.2 and then when I took my temp again a couple minutes later it said my temp was 97.7
