Good idea but poorly executed locally

For sensor mat I must first say that it reliably fulfills my opinion their job. But what the developers have thought at the baby monitor and the operation?

Negative points:

-The Display has an extremely limited viewing angle and can not be dimming

-Have Had on 4 of 8 radio channels in just 2 days extreme interference (radio, music, ...) and in a small village

The most annoying thing, however:
-There Is a function (Hold) in which a key is pressed on the receiver and the unit "Paused" is (eg if the child is removed from the crib to breastfeed)
At the transmitter then reminded but a sound every 60 seconds because you yet again turn it thinks to do when you put your child to bed again. Actually a sensible idea but not so forgetful people like us
can this sound does not stop or regulate quieter. This means that I as a father would constantly annoyed by this signal.
