Thought this product was a great idea for Moms/Dads on the move but it simply doesn't work. I live in an apartment and have the standard Fisher Price Sounds n' Lights monitor which has worked perfectly for us for 2.5 years. I bought this for our second baby due in October and tested it out today. After a full charge, I wore the monitor bracelet in our bedroom and immediately began hearing lots of static and a popping noise, followed by loud beeps that drove me nuts. The rooms are not more than 50 feet from each other. Sadly returning this product and will continue to search for something that works for us.
