works well! sometimes ... :)

the indoor test has shown exactly what I was looking for.
easy to use and above all very comfortable with remote control.
Everything worked reliably and the volume is more than sufficient in my opinion.
similarly, according to the smoke detector in the living room and that's enough for any occasion.
However, you should wrap the alarm niergends. already a thicker plastic bags can range in order to reduce the volume enormous.
Conclusion: function as described, reliable, small, light, loud - perfect!

the outdoor test but then another side of the alarm revealed :)
once the alarm does not respond to the transmitter, once.
quite annoying when you try to trigger the alarm and can not turn it off him. no matter how far you are away with the hand-held transmitter.
I thought at first only to a problem with the battery and have changed this.
here please caution: I was cycling and had to make watches in which the batteries cast 24.- have cost.! at mail-order companies are much cheaper to purchase (see comment on this review)

Well, batteries changed and tried again. 2.te each keystroke remains without success.
sometimes it did not work, so I've stopped using it entirely. Indoor it works but still fine.

da ich mir das nicht erklären kann und somit nichts unternehmen kann um das problem zu lösen gebe ich den alarm zurück. since indoor everything is perfect, I do not think that this is "Monday device" is a and try another solution.
