+ Very well (measured value agrees with subjective feeling and fluid intake in line; also the degradation rate is very real and constant)
+ Very handy, fits in any pocket or shirt pocket
+ Very easy
+ Display easy to read
(Press and hold the central button to turn the unit for about 2 seconds, wait 5 seconds and then the tester is already ready) + very easy to use
+ Device turns itself off when not in use itself
+ Contain "private" mouthpiece in the machine (is carried by a slider at the top edge of the device)
+ The signal to stop the Pustens is not a high-pitched signal, but the Tester vibrates slightly
0 it means one should not drink alcohol 15 minutes before the measurement and do not smoke. The former is true, the latter is not. Even though I smoke a cigarette in between and then execute a measurement, the nicotine does not change the measured value.
0 while providing no 25 Replacement mouthpieces nor Kalibriergutschein were included. Send an email to the seller ACE technique was answered very quickly.

Manufacturer recommended every 6 months, but not later than every 12 months.
