Is this the best Germany (if then this even truly is made there?) can do in 2016? This one's even worse than another I had, not by this manufacturer, not under this patent, perhaps not with "galistan" or w... it's called? That one I had a couple of decades ago: in other words, the concept of non-mercury thermometer is also not exactly new! That one took about 3mins to take temperatures and was somewhat stubborn to shake down, but doable! This one's already refractory when taking the temperature (5mins+) and downright pig-headedly obdurate, whilst challenging your elbow and tendons on the way down.
I'll keep it as a confirmation/backup for a little digital one for high temperatures (or should the battery go on just such a day). But if I were too use this too often, I swear I'd get "thermometer arm" and my GP would tell me to stop playing golf (which I don't).
This takes your temperature - with a bit of luck for the rest of the day (which is why I gave it two stars, not zero). It also takes longer than a mercury thermometer. When I was a kid, 3-4mins did the trick; I've not managed to get this one under 5mins (more seems better) for temperature readings of any interest or accuracy. And, put politely, I am old enough to claim without hesitation that I know how to reset a 'proper' analogue thermometer in 2-3 strokes, not 20+. Maybe there's a new technique for these, but the old method positively is unhealthy on this model. I should do a search on YouTube.
Talking of searches, eBay UK only yielded old Fahrenheit mercury thermometers, but the German eBay has plenty of Centigrade ones from the 'good old days', ex-USSR stock, &c. I'd just be concerned about disinfecting such old glass - but still considering it.
Last but not least: If this is the one with the XL-scale (as the box claims), I feel sorry for the poor buggers that have bought the standard scale version. It's quite readable, but it's NOT extra-large print! At least that means it's also slightly smaller on the whole than old mercury thermometers were.
I gave it two stars only because it actually showed a very realistic temperature and perhaps that it is a little smaller than old 'quicksilver' ones - other than that it deserves one or zero and I don't see a need for it having been patented. Nothing to brag about!
The product arrived really quickly (on the second day after purchase); I tried it immediately, and compared its result with an electronic thermometer. I left it nice in place in my underarm for roughly 10 minutes, and it gave a plausible result; the temperature mesured by the electronic one was 0,5° C lower (36,1°C vs 36,6°C, the last one being more likely to me). After mesuring the temperature, I lowered the Galinstan column as usual, without any effort at all.
I absolutely recommend this product, identical to a classical Hg thermometer apart, of course, from the mercury.
I bought 2 a few years ago, but broke one.
I bought two again, so I have 2 spares. Actually I sometimes use one orally and another one in the armpit at the same time. It's interesting to compare.
I don't think they are that difficult to shake down when you've done it a few times. It needs a certain minimum force/speed and a definite flicking action.
Interesting, the first 2 I bought only had Celcius, with even degrees on one side, and odd on the other.
the ones I bought recently had Celcius on one side and Fahrenheit on the other. useful to have Fahrenheit, as so many US reference sources use it. On the other hand, the Celcius-only one is slightly easier to read I find.
This thermometer seems to be fairly accurate (compared to my electronic one) and there's not a lot that can go wrong.
