Since my Cyclotest has given up the ghost, I have now decided for the Domotherm, it resembles basically also the total Cyclotest.
It measures even after the beep on, which is important for NFP. That the final temperature is stored even after switching off, it is ideal when measuring sleep in (half) and after waking up its temperature measures.
As was already grumbling about the loud beep pushy here, I want to also say something.
The beep when switching could be louder in my opinion, as I have just half asleep exhibition in the dark and will be sure that the thing is at.
Ok the beep at the "end" of the measurement process is very noisy, but you get used to it and if the sound is suddenly silent, one can assume that the battery is no longer optimal, thus quite useful for me and not a shortcoming.
