owlet monitor

Has anyone used this? I want to have something like this to ease my mind but I also would like to have a video monitor, we just moved and our daughter's (my stepdaughter) room will be on another floor so we would like to keep an eye on her too. I thought about an angelcare monitor because it monitors breathing and has a camera but we can't add another camera. So this was my next thought, getting a monitor with two cameras and this extra monitor for the baby.
