Customer Reviews

Great Thermometer!
I think that this thermometer is great. Unlike the other 2 reviewers, it was easy to shake down, and it was very accurate at measuring my temp. In comparison, I find that digital thermometers are a total waste of time and are completely inaccurate for BBT charting. It is also great becuase I accidentally broke the thermometer and I didn't have to worry at all becuase it is mercury free!

Confusing at first, but looking good now!
I originally thought the 'mercury' in this thermometer was impossible to shake down, and was ready to send it back and buy a digital one. After speaking with a very nice man at the manufacturer, he suggested I tap the thermometer down onto a post-it note pad at a 90 degree angle (holding it as if I was throwing a dart into the pad) and see if that helped. Still no luck.

...then I realized the blue line I was seeing was a permanent mark on the glass, and the 'mercury' inside was actually silver, and not even registering a temperature. Doh!

After recognizing that it was my own idiocy that was making it "not work," I just sat here and took my temp orally (not a true basal temperature, but just to test it out) and got a reading just fine. The temperature is a LOT easier to read with the magnifying case, so definitely use that. It requires a little rocking back and forth to get the line to appear clearly, but the numerical markings are large and easy to read.

Now, the moment of truth: I attempted shaking it down, and had it completely down with about fifteen easy shakes. Definitely not the problem I thought it was!

So far, so good. I'll be giving this a tentative four stars, and may come back and change that after I use it for a while and either love it or hate it. I know it's going to be a bit of a pain to read the thermometer in the dark, wait five minutes for it to register, and so on, but those are things I accepted when I bought it in the first place. As of right now, I think I can recommend this to others on the condition they understand it's NOT a digital thermometer and therefore isn't going to be as convenient!

Hard to shake down
This is a very nice, sturdy thermometer with a handy feature of the magnifying case, which makes it easy to ready the temperature. HOWEVER, it is very hard to shake the "mercury" (the fake mercury) down! I have used regular mercury thermometers in the past and have never had this problem. This is a particular problem when you are charting and taking your temperature every day. Maybe there is some trick I don't know about, but i doubt that shaking a thermometer down is rocket science! I'd appreciate any tips!
