Q: Are you supposed to add one degree for an accurate reading??
submitted by HCG - 3 years ago
A: Hello, and thank you for reaching out. When using a forehead measurement, it is expected to be lower, anywhere from 0.5°F to 1°F lower, as it is an external reading. Furthermore, forehead temperature reduces with age, the older an individual, the lower the forehead temperature is expected to be. Therefore if it is recommended to use these devices as a strong indicator of current temperature, learn your own normal reading so you can identify if a result is outside of your normal temperature.

Q: Is this only able to take readings from ear/forehead? An answer from MOBI says so but the highlights state otherwise.
submitted by Michelle - 3 years ago
A: Hello Michelle. Thank you for taking the time to reach out! The thermometer has three different reading features. The third feature that the thermometer can read is food and object temperatures. To read these temperatures, press down on the HEAD and EAR buttons together. Hold the thermometer 1-2 inches away from food or object. Then press and release the EAR button to scan. Please feel free to reach out to us via our online support desk if you have further questions.

I purchased this recently when my child got sent home early from day care. I was told that he had a fever, so I stopped to purchase this one as the one I had was the regular one. Well this thing always read temperatures of under 95 degress. Nothing ever at normal temp. I restarted it and it continued to do the same thing! do not waste your time or money on this!!!

Isabelle - 3 months ago, Verified purchaser
I specifically bought this for the ease of taking a temp on my 1yo and the language on the packaging was promising which specifically said "doctor recommended", but when I was using it to determine if my son had a fever, the thermometer said his temp was 98.6. I took it rectally, and it was 103.7... The fact that this was so inaccurate was dangerous. If his fever was any higher, it could have warranted a hospital visit. DON'T BUY IT!
1 reply from MOBI Team team - 3 months ago
Hi Isabelle, sorry for the trouble. Forehead/ear readings can be affected by factors like environment, positioning, or sweat. Rectal readings are more accurate. Please follow the instructions provided for best results, and contact Support if issues persist.

Completely inaccurate; normal temp reads around 96 usually, and despite my daughter having a fever (w an under tongue thermometer), the one still showed about 98. Putting inside the ear seems a tiny bit more accurate but the forehead is way off.

I do not recommend this item. I was using this item tracking to my toddlers temperature. All day, from the time I picked it up to the last time I used it. I was getting g a safe reading from 98.2-98.8. That was false, my toddler was fevering. Her real temperature was 105.3 (rectal), right before this the thermometer showed 98.8. She had a fibril seizure. Don’t buy it. The emotional and mental damage was horrible. And my poor child was suffering and I let it happen by using this item.

Hello, We are truly sorry to hear about your experience and the distress it caused. Your child's health is the top priority, and we understand how concerning this situation must have been. Infrared thermometers can sometimes be affected by factors like positioning, ambient temperature, or sensor calibration, which may cause discrepancies in readings. For more accurate results, especially with infants, rectal thermometers are often recommended. We deeply regret that this product caused you unnecessary worry, and we encourage you to reach out to our Support Team for assistance or device exchange.
