My first purchase was fine: 'blue line" was visible front and center, and it "shook down" just fine. I ordered a second and couldn't see a "blue line" except from the side, and I couldn't "shake down" that side-visible line. Following another reviewer's suggestion, I took my own temperature with this 'broken" item and the proper blue line appeared, front and center. SO, for those who think their item is broken, try taking someone's temperature for 3-4 minutes to see if the blue line appears, and THEN shake it down. Orig: Unlike other reviewers, I had no more trouble shaking down this thermometer than my "old fashioned" glass mercury thermometer. It does take quite a snap, but they always did, didn't they? I put this and my mercury thermometer in two sides of my mouth at the same time and they measured within about 0.8 degrees of each other. (In other words, less than 1 degree F apart, which is good enough for me as I don't know which is more accurate or whether the two sides of my mouth were diff't.) I DO shake it over my lap with a blanket or over something soft in case it accidentally comes flying out of my fingers. It's glass according to this product site, but so lightweight I couldn't tell whether it was plastic or glass. The cap is neat - look inside it to see 'fins' that you can ease the wide end of the thermometer into such that the cap will hold it, even placing the cap upside down. I find this handy to air dry completely after washing it since I don't want to cap it with moisture inside (tho case has a hole at bottom so it's not airtight, which is good). I was thrilled to find these for my roving first aid kit since: (1) I didn't want to depend on batteries for a vital tool that may not get used for months/years at a time, esp while camping in remote areas, and (2) This item is much smaller than the typical digital thermometer, for storing in a tiny kit, and (3) I'm presuming this item is more accurate than the "average" digital thermometer, since I've researched, purchased, and used several digital thermometers and they were frequently 2 or more degrees off from each other. This brand seems high quality from the wee bit I've read about them. Review: I compared five medical fever thermometers - SEP 28, 2020 -- I compared five medical fever thermometers, patient awake (20 minutes after waking), in bed, under a sheet and light blanket.

Put the thermometer in a longer sock with the tip down, and twirl it for 5-10 seconds. The centrifugal force gets it done> I had 2 glass ones I couldn't shake down and they both went way down to the bottom. **Q: Can you shake it down at night for a morning underarm reading?** A: That’s what I do. I shake it down before I go to bed. In the morning, it’s ready to take a morning underarm reading. I tried using it under my tongue, but I’d fall back asleep and it would drop out of my mouth. Securing it in my underarm works great. My alarm clock snooze lasts 5 minutes, which is just enough time to get an accurate reading. Shaking it down using the sock twirling method has worked super well for me over the years! **Q: do you have underarm mercury termometer? i used to live in Ukraine, those were very good, if broken--as children used to play with balls..lol** A: Dear customer,Apologies for our late reply. Your query was missed by our Customer Services Department over the Easter break.Thank you for your interest in Geratherm Classic, this thermometer does not contain Mercury but Galinstan, an alloy of gallium, indium and zinc that replaced the mercury.The old fashion thermometers contained Mercury. Mercury Thermometers are now banned from many markets including Italy, France, England and many other European countries.Thermometers with Gallistan are therefore the only alternative to the old analogue thermometers and Geratherm, our partners, are the company that holds the worldwide patent for this product. Any other analogue thermometer mercury free on the market, not Geratherm, is illegal and Geratherm has implemented various procedures with the manufacturers of these thermometers in order to protect its patent.We hope you are still interested in our product. Geratherm Classic can be used axilary, rectal or oral.Please let us know if any queries.Kind RegardsCustomer ServicesPISPO ltd. **Q: is this liquid metal or liquid alcohol** A: This product contains Galinstan, which is a liquid metal alloy mainly composed of gallium, indium and tin. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works just like my mercury thermometer - sturdy, packable, 'accurate' and no batteries req'd *by S***L on February 1, 2019* Update: Second order APPEARED BROKEN but wasn't.

I was hoping it would be doable, tho. However, the one I got simply wouldn't come into the readable range. I tried shaking it. I tried the sock method and did a count to 30. Didn't budge, so I set a timer for 25 seconds and twirled it according to the recommendation of other reviewers (and my wrist and arm know it, too!). Didn't budge. So I put the tip into ice water for the next 9 minutes, checking it every 30 seconds to catch it before it got too cold. It didn't budge. Am returning it, and going back to digital. Also, the diameter is quite a big larger than the old-style thermometers a lot of us are used to from a decade ago. The shipping was fast, tho. ## Frequently Bought Together - Geratherm Mercury Free Oral Glass Thermometer, 1 Count (Pack of 1) - Boncare 10 Seconds Digital Thermometer for Adults and Kids - Accurate & Safe Rectal Thermometer for Baby with Fever Alarm, Oral Thermometer FSA HSA Eligible (Dark Blue) - Boncare 10 Seconds Oral Thermometer for Adults and Kids - Accurate & Safe Rectal Thermometer for Baby with Fever Alarm, Digital Thermometer FSA HSA Eligible (Light Blue) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/9282903-geratherm-mercury-free-oral-glass-thermometer-1-count-pack-1](https://www.desertcart.us/products/9282903-geratherm-mercury-free-oral-glass-thermometer-1-count-pack-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-04*
