Advantage 1: No false alarms are handled properly. Whether one or two sensor plates: while moves in the bed something, even if only minimal - unless an alarm goes off. Without having anything set (sensitivity, etc.)
Advantage 2: Battery operated - and keep for months (we already 5 months)
Advantage 3: The alarm can be heard clearly even through several rooms, but (off forgotten) even if he starts right next to the ear at night it's bearable and not the whole family startles.
Advantage 4: The alarm also goes off if the motion rate (= respiratory rate) falls below a certain value. For other manufacturers, only a certain period of waiting is "silence". This device is in absolute calm a clunk, whereupon the alarm follows; and at a reduced frequency of movement of the alarm goes sometime directly going without warning.
Disadvantage 1: When enable you hear "click" - sensitive babies waking them possibly on (mine not: D)
Disadvantage 2: The device is so sensitive that you should be careful that no parental duvets or other motion vectors (fans, vibrations of washing machine etc.) get to the crib, otherwise the alarm is delayed by certainly 30 seconds or more in case of emergency
All in all, I was always glad and happy to see the member beside me flashing in the dark)
