I have originally purchased this for my upcoming daughter, and I did some tests on my elder one and find it really gives me peace of mind.
First of all, it is easy to set up and all you need to do is download the app. On the app, it tells you whether she is breathing, did she rollover, or what temperature she is on now. I would strongly recommend this product to those new born's parents especially if you are the first time parents.
