Geratherm Mercury Free Oral Glass Thermometer, Pack of 2

I agree with other reviewers that those who complain are probably revealing their inexperience with glass thermometers. I bought the two pack, and their readings are consistent with each other, and they yield temperature readings very close to my better digital thermometers. You need to shake down the liquid before taking a reading. The liquid in this thermometer is significantly more difficult to shake down than the old mercury thermometers, I presume because mercury is much more dense than this liquid. One reader said it works to put it in a sock and swinging it rapidly. Also, they are fairly slow. It takes 2 or 3 minutes to get a good reading. The drawbacks are simply due to the nature of glass thermometers. However, the fact that they don't need batteries means they will always work. The batteries in digital thermometers seem to give out at the most inopportune times, so it's really nice to have a glass thermometer handy as a backup. Note: Amazon's "Rate Features" section for this thermometer had "Accuracy," (which is fine), and "Warmth," and "Thickness," (which is just plain weird).

I’ve seen the negative reviews about the line not going down and I thought I was in the same boat. But I discovered two things: 1) you have to rotate it back and forth to catch the correct angle to actually view the reading. Otherwise it looks maxed out. And 2) it takes way more than a few shakes to get it to go down. Hold on tight and wag that thing for 60 seconds and it will work. I calibrated it against our rapid digital thermometer. It reads a half degree warmer. But readings from this device are more consistent.

Whoever wrote that this is hard to shake the temp down must be used to only using digital thermometers. It shakes down pretty easily but then again I’m used to old school stuff, not getting everything right away. It is a bit larger than your average thermometer but again, I can cope with a little obnoxiousness. It’s also mercury-free which is great, so if it breaks you only have to worry about swallowing glass. Thanks to this little guy I found out my digital thermometer was giving me a false temp (higher) have the time….Only bad news is, I’m returning this one (unopened, don’t worry) because I found the same exact item for $5 less at Rite Aid. I just had to walk there and get it and find out I didn’t have a real temp after all. Yay me!

I love the old fashioned simplicity of this product. No batteries to wear out or wonder about… no error messages… just stick it under your tongue and wait a few minutes. Then look at it again. My instinct is to trust German precision engineering and manufacturing. I’ve had one of these for many years, but one time had trouble finding it in my bedroom for awhile. So I decided to get a couple extra to have on hand just in case anything should really happen to the one I had. Grateful to find this product still being sold.

I had the same experience some other reviewers noted that these thermometers worked the first 2 times we used them, but after that now they will no longer change from wherever they were shaken down to -- they will no longer indicate temperature. And now the return window is closed. Don't waste your money! If you use them a couple times and then are depending on them if you or your child are sick the next time and they don't work, you'll be out of luck. They were also immensely difficult to shake down after the two times they did work. We had to put them in a sock and use centrifugal force because shaking them down by hand was futile (and we've always been able to shake other thermometers in the past.) I'd give zero stars if it were an option -- thermometers need to be reliable!

I have a disabled daughter who has had several brain surgeries in the past and has a temperature gauge problem in her brain where her thalamus does not properly regulate her temperature. I have purchased tons of the expensive easy to read thermometers over the years and over and over again, they have failed and they are inaccurate. When all else fails, go to what works!!! I purchased 2 of these mercury thermometers and they are so accurate and work well. I will be purchasing them from now on as I have given up on all the other expensive ones that seem to give us a different temperature with every read!!!

This type of oral thermometer is the most accurate type compared to the battery thermometers. It is the only kind I trust to get the true temperature. For me, the battery ones have a different temperature reading within a few seconds of each use. I have been using this type thermometer for 40 years. I was only able to find this type at Rite-Aid, and now Amazon. Great Accuracy.

Three stars. Ahhight. Well if you want an old style thermometer you may be like me and want one for your field first aid kit such that you don't have an item which has batteries that can go dead in your kit. So. 1. Yes if you leave it in your mouth for an uncomfortably long time it will accurately tell you whether or not you have a fever and how bad it is. 2. Yes it's reasonably easy to read so long as you have it turned just so, such that the liquid column is magnified. 3. Yes it holds the liquid in place until swing it around violently such that you have time to turn the thermometer just so and read the temperature. 4. It comes with a nifty plastic case (best part of the thermometer in my mind) that protects the thermometer when not in use and aids in holding it. Ok the temperature graduations go fro 95F to 108F. So they've got fever and heat stroke covered all the way up to likely to kill you. However, 95F while technically hypothermia is "have a cup of coffee and a blanket and quit whining" hypothermia. I think this is a huge missed opportunity. I suspect that many out there whom want a non-electronic thermometer for measuring body temperature are like me. They want it for a field first aid kit where an electronic thermometer is just a pain in the butt. Now while hypothermia is an outlier of reasons why you want to take someone's temperature in the home or usual healthcare setting, it is much more common in the wilderness where accidental exposure to extreme cold can happen for a variety of reasons and exposure related deaths are common. As such I need to know when hypothermia is more than an annoyance and represents a true threat, i.e. where the condition is potentially life threatening and extraction/evacuation and aggressive warming measures need to be considered to save someone's life. As such the range needs to dip into the 80s, around 85 would make me happy. This thermometer outright fails at being able to diagnose the severity of hypothermia. So it's only three stars.
