Like another reviewer, I thought this was a great product for the first year or so. After that, we started getting incredible static & crackling on the receiver - to the point that we need to fidget with the unit for 5-10 minutes before we can actually hear our son. We also get a huge amount of feedback if the receiver gets anywhere near the base (i.e. walking past the nursery room or even directly beneath the nursery on the 1st floor). Other than that, it's really been a great product. Just beware that after a year, you may need to replace it to keep your sanity!
