We chose the Angel Care 420 because of the good reviews. Meanwhile I cry every euro after we've spent (quite expensive) for this baby monitor. In my circle of friends or anybody else this baby monitor and all have similar problems: constantly disorders, regardless of which channel, which superimpose the actual baby reception, or the unit alerted suddenly as it "allegedly" has no connection to the transmitter. Young parents know how grateful you are for sleep every minute, but sleep to us begrudge the little one, takes us Angelcare. I regret to say I würds definitely not buy it again.
