I have found this baby monitor to be really good. The basic design of the parent unit is more akin to a cordless phone as it sits in a cradle to charge, uses the same digital technology and has an intercom facility.
The clarity of the sound can't be faulted either and while I really only used the intercom feature to poke fun at my wife while she was in the child's room, the sound quality of her less than impressed response was crystal clear.
I have found a few scenarios where some specific features have come in useful. (apart from the intercom). The sensitivity of the child unit can be adjusted to remove background noise in the room, particularly useful in summer if you have a fan going in the child's room.
The battery backup in the child unit is useful for power outages as we've discovered, but also if you're visiting somewhere and there isn't a mains point handy.
While the temperature alarm is really useful in the winter time (and to a certain extent, the rest of the year), be mindful of the temperature alarm settings in the summer. There's nothing more annoying than the temperature alarm going off when there's nothing you can do about it. (Unless you believe the x-men are real and Storm is your next door neighbour).
Until recently I hadn't really used the lullaby feature, but now our son is almost two, he thinks it's his own personal radio. Not normally a feature I'd look out for.
All in all, it's a pretty decent little pack. I'd recommend it to anyone.
