I received this from my best friend that had a baby 7 yrs ago!! It works great. Being a first time mom I was wanting one of those monitors that can track a baby's breathing. I looked at the ones that you attach to the baby and the ones that he would lie on. But I did not have 100 or more to spend on it at the moment. I got this one set up and was amazed at how clear I can here. i was able to place the monitor right next to him (probably not recommended) and here him breathing. That kept me calm over those crucial first couple of months and I was able to sleep better. I also now sleep with it under my pillow to here him with out it disturbing my husband to much. It really has been a life saver. It has even taken so abuse as in being dropped a lot or pulled out of the wall when it is plugged in. On one of the receivers that I use around the house something it is rattling when you shake it but it still works. The one by my bed has ended up on the floor at least once a week and it still works perfectly. When I was on maternity leave I was breast feeding him in the bed room and had the monitor on and could here you husband talking to our friends in the kitchen and could clearly make out what they were saying. Our sons bedroom is at the end of the hall and is probably 40 or 50 ft from the kitchen. The only thing wrong with it is that sometimes it can pick up to good. Maybe other monitors would to but at night I can here the dish washer but that does not muffle out him when he makes any kind of noise but it is a little harder to decipher his breathing from it.
