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.

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.

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 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.

Love these thermometers. The cases are strong and well designed. The thermometers seem extremely accurate and quite quick. I'd highly recommend the sock trick for zeroing them out, works in just a few seconds. You can do it with them in the case. Love them, think they'll last a very long time.

Like the finer details but very difficult to shake down for next use.

Title says it all, still got charged the full price of $19.68 CAD pulse $15.21 shipping even though I am a prime member with free shipping. So a total of $34.89 CAD for one thermometer. Very disappointed.

Ordered 3 of them and they are very good but one came broken. Hope seller can replace it.
