    Inaccurate readings (even with fever)

    Ordered this before daughters dr appointment, already knew she had a fever and we would need to monitor it at home. It got delivered while we were at the dr office. I get home take her temp again and it’s 97.2 so I check myself and it reads 97. Completely inaccurate going to return. Don’t waste your money!

    Inconsistent readings

    Tried multiple times all different readings
    1 reply from MOBI Team team - 1 month ago
    Thanks for your feedback—we understand your concern. Inconsistent readings can happen due to slight changes in placement or sensor position. For best results, use the same spot and wait a few seconds between readings. If the issue continues, please contact us at service@getmobi.com —we’re here to help.

    Inconsistent measures. Any part of your forehead will be a low number, 97.9 and then the next reading will be 101.6. Don’t waste your $
    1 reply from MOBI Team team - 1 month ago
    Thanks for your feedback, Autumn—we understand your concern. Large differences in readings are often caused by inconsistent placement or scanning technique. For best accuracy, use the same spot on the forehead and allow a few seconds between readings. If this continues, please reach out to us at service@getmobi.com —we’d be glad to help resolve this for you.

    Horribly inaccurate readings . I read the reviews but still thought I’d try for myself . I wish I listened 94 to 97 to 98 to 101
    1 reply from MOBI Team team - 1 month ago
    Hi Nell, Thank you for your feedback. Temperature readings can vary if the sensor position or distance changes between scans. For best results, ensure the sensor is properly placed on the center of the forehead or correctly positioned in the ear, and that the lens is clean. If the issue continues, please contact us at service@getmobi.com and we’ll be happy to help.

    Do not buy

    I have read and followed the directions and I cannot get this thermometer to take a temp. My child who has a fever is getting a "Low" or "error" reading. I've tried it on myself and I get the same readings. I've tried the forehead scan and ear scan.

    Hi Allison — we’re sorry to hear the thermometer didn’t deliver the accuracy you expected. For best results, make sure the sensor is clean, the device is positioned correctly (ear or centered on the forehead), and both the thermometer and user are at room temperature before taking a reading. If it’s still not performing as it should, we’d be happy to help with troubleshooting or warranty support. Your confidence in our products is important to us.

    Beware

    I’m not sure I would even give it a one star. So disappointed and ultimately dangerous especially if using on children. Inaccurate readings. Ended up in the ER with a kidney infection running a 101 degree temp despite the thermometer reading 98.6 over and over. Do not buy. Spend a little more for a better one. Will give credit for design versatility but what’s the point of the reading is inaccurate.

    Inaccurate Readings

    Inconsistent and Inaccurate readings. temperature always displays low. got a reading of 96 from this thermometer, checked with an under tongue thermometer and got repeated readings of 102. You can't even count on it being consistently wrong.... it's just all over the place.

    We’re very sorry to hear about this experience. A difference like that is understandably concerning, and it’s not the level of performance we expect from our product.

    Don’t buy this, it isn’t accurate. Will check forehead and temp will read below average and then check ear and be around average, then checked behind ear or of curiosity and temp read high… so not helpful at all. Will be returning.

    This thermometer is the most wacky thermometer I've ever used. I do three temperature scans every time I use this because they are always so sporadic. it's told me that my temperature was 105° at one point in time and then on a different part of my head it told me that the temperature was 95°. if you want a thermometer with a temperature you can trust, don't use this thermometer.

    Inconsistent Readings

    As others have said - inconsistent readings. I follow the directions and make sure no hair is in the way, that the thermometer is placed correctly, etc. but I still got wild variations. Two nights ago I got a reading of 103, was very worried, then got readings of 101 seconds later. Tonight I got a reading of 102.1 then 101 something, then 109 something, then 99 something. At this point I don't trust this thermometer at all and we've only had it 7 months.

    keeps giving different readings each time you take the temp. also doesn't match up to other thermometers when temps taken at the same time in the same location.
