Works flawlessly. Switching, for example, pinch under the armpit and after 9 seconds, it beeps. The measurement is done. The digital display is very good and clearly illustrated and readable, even without glasses. Then simply turn off equipment. When switched back on, the last measured value is displayed, it will flash and you can re-measure.
After about 25 measurements, a new icon appears in the display and the device you have to download about 1 hour in the light. So much time indeed has a first measurement actually getting. Now we have a thermometer on which we can rely, because batteries are no longer an issue.
A German brand just; thoughtful and perfect quality.
Tip: The manual is indeed clear, but a bit small in Scripture. Simply copy or scan up to 200% and on two A4 pages is all to read without glasses. Abheften So the guarantee documents or wherever desired store.
Five Stars.
