THanks Teagz,
'fo shizzle' - i luv it
I bought it! WOOHOO
Now of course my mother (from hell) is now telling me how so and so at work says they are absolutely useless and go off all the time etc etc.... i'm like, everybody swears by them, maybe she has the thing set too sensitive or is using a fan or something at the same time... Gosh my mother would find something negative to say about anything i do! grrrr.
However, I AM HAPPY WITH MY PURCHASE...

THanks all for your advice.
My SIL has had one go off once randomly about... 5 years ago. And I'm not ever sure if it was an angelcare one, and I'm pretty sure it was a set up issue. I think they would have come along way since then, anyway. My other SIL who has a 12 month old has had no trouble with hers what so ever. My MIL traditionally buys baby monitors for your first baby and this is was she reckons she's getting for us!
