This monitor has a lot of static on it, even when used with the AC adaptor. Took me awhile to get used to sleeping with it on. My biggest problem with it though is that the turn button for the volume is very hard to adjust...you just can't get a good grip on it and is very difficult to turn which really aggravates me. The only good thing about it is the two recievers, but I'm certain you could find a superior product.
