℃&℉ Oral Thermometer for Adults and Kids 2PCS - Glass Rectal Thermometer for Baby - Basal Body Thermometer - Non Infrared Digital Thermometer - Accurate Easy Reading by HARIKA LIFE

I wanted an old school glass/mercury thermometer and that is what it is. Was tired of electronic/battery devices that are not consistent on readings, even when done close together. It’s a little difficult to read - just have to twist it until can see the reading. Also have to shake the mercury level down before using. I’m happy with it!

I’ve ordered these glass thermometers twice hoping I had a defective item the first time. NOPE both times the product did not work.There is a narrowing in the tube the doesn’t allow the liquid to move within the thermometer when placed in hot water to test. I first ordered these in the summer and didn’t try the product out until I was recently sick and found out it was defective.Amazon has a horrible return service, there was no way for me to get a full refund or replacement with the amount of time that had passed. Walmart.com is much better with customer service in comparison. Take your business elsewhere and save yourself the hassle!!

It is always good to have a backup thermometer for when the digital thermometer is not working properly. I was recently ill and I compared them. I found the same temperature on both this thermometer and the digital.

Hard to read results. Numbers are too small.

I compared these glass mercury thermometers to a known accurate one I have from a USA manufacturer (the white one in my photos). After several side-by-side accuracy tests, these thermometers were slightly low by about 0.2°F and 0.4°F comparitively. The print of these thermometers is a bit inconsistent and difficult to read, but the background color and the mercury line itself is easy to see so the ease of use is mixed. I noticed that the print between the 2 thermometers does not align, so there is either a quality control issue with their calibration or with the print application process. Overall they are still functional and I haven't had a problem shaking the mercury down like some others users noted.

Don't know what it is about the digital thermometers, but I've had an awful time with them going bad.Need something accurate and the old style doesn't fail.

I use to use these all the time until they came out with digital. I wanted to go back for the reliability. I cannot find the line on this. My entire family tried to find the line but was not able to find it. Do not recommend

Happy with the purchase
