This monitor gives you a way to actually BUY peace of mind. I'm a light sleeper, and when my baby started tummy sleeping, I was getting no rest. With this monitor, I know that I will be awakened if my child is no longer breathing, and that to me is priceless.
This baby monitor is easy to set up, and really works. When you use batteries, there is a bit of static, but I found that problem easily eliminated by using the adapters. It's nice to know that you won't have to replace the batteries all the time, and that it won't stop working in the middle of the night. It's very easy to use. Literally, just the flip of a switch and your baby is being watched over by the angelcare system. There is an optional ticking feature that makes a noise every time the baby moves. I would recommend not using it. It will drive you batty, but is a great gift for the super-paranoid!
The Angelcare baby monitoring system is very parent-friendly. It allows you to choose your sensitivity level, and it's easy to adjust. You will get the occasional false-alarm when your child wiggles away from the platform, but not so often that it is a problem. You just move them back and off you go. I was skeptical of this product at first, but it really does detect every little breathe your little one takes, and you can count on it going off after 20 seconds of no movement. For me, this product has been a blessing I could not live without!
