1Pc Glass Oral Temperature for Adult, Old Fashioned Armpit Termometro Fast Reading for Baby Armpit Home & Clinic Fever Indicator (Fahrenheit & Celsius)

I bought this because my battery-powered thermometer turned out to be dead the last time I tried to use it. Either the battery died on its own or a failed to turn it off before putting it away the time before. Since it uses a hearing-aid battery that took three weeks to appear in the local store last time a new battery was needed, I decided to go retro. I have not actually used this so cannot speak to how accurate it is. Frankly, consistency is more important to me anyway. But I can say this: 1. I have no reason to believe this is not a new unit, properly assembled and well-packed. 2. I did have problems shaking the temp down. I put it in the refrigerator (/not/ the freezer!) for a while. It dropped some but, more usefully, it then responded to being shaken by actually moving the mercury down the tube. Whether this is only needed the first time or will always be needed is unknown. So I am happy with my purchase.

I purchased this thermometer for my son to use at university. It turned out to be a complete nightmare and a potentially dangerous product. For over a week, this thermometer consistently showed my son's temperature as 38°C (100.4°F), indicating a fever. He felt perfectly fine, but trusting the reading, he started taking fever-reducing medicine daily. As the "fever" persisted, we grew suspicious. We decided to buy a new thermometer from a different brand. To our shock and anger, we conducted a simultaneous test: the new thermometer showed a normal temperature of 36.8°C (98.2°F), while this old one still falsely read 38°C. We finally confirmed that this thermometer is completely inaccurate. It caused us unnecessary worry and led my son to take medication for over a week for a fever he never had! This is utterly unacceptable and could be a serious health risk for others. I am writing this review to warn other consumers. DO NOT BUY THIS THERMOMETER. It is unreliable and dangerous. Save your money and, more importantly, protect your health by choosing a different, trustworthy brand.

The 1Pc Glass Oral/Armpit Thermometer is a classic, analog medical tool designed for those who prefer the consistent reliability of traditional methods over digital sensors. It features a dual-scale display for both Fahrenheit and Celsius and is commonly used in both home and clinical settings for adults, children, and infants. This old fashioned thermometer requires more patience than modern infrared "guns," but the peace of mind regarding its accuracy makes it a "buy it for life" staple for many households including mine.

I love getting back to easily read thermometers. Tried and true...no batteries!!

This item is too big to fit under your tongue. So you can not get an accurate reading. I bought two hoping to put one in my travel bag but, it’s useless. So now I’m stuck with one that hasn’t even been opened.

Wish they made thermometers as thin and inexpensive as they used to be. This works well, easy to read. Seems like it will be durable - my old one was the old kind and broke when it fell on my tile bathroom floor. Only downside is that it's about as thick as my finger - harder to keep your mouth shut around it!

Love love love love

I could not get this to work initially, even after shaking it down, running it under hot and cold water, or placing it under my armpit as directed. The indicator would not move at all. I set it aside for a couple of weeks, and was about to throw it out (not worth the hassle of returning it). And when I shook it down, IT WORKED!
