Easily the most reassuring piece of kit we've bought regards our new baby (back in 2008) & we still use it now. Its a good picture, although there is a slight interference whenever we're using the fan oven downstairs (!). But great on a practical level as u can just monitor how your kid is without popping your head through the door & waking them up. I've even used the "talk" option on the handset which is hilarious - "I'm coming to get you - it's time to get up", "Ok Daddy!" All of our parent friends have commented on how great it is.
Recommended for all worrying parents!
PS: I dont really get what the other reviewers are saying about interference, unless they live in old cottages with v thick walls or next to Picadilly Circus.
