We LOVE ours. We have the angelcare sound/movement but I wanted something that I could use once he got mobile.
We bought the motorola 2.8" screen monitor. The picture and sound quality is fantastic and the battery life holds up well. There is also the ability to add another camera in the future. There is no downside IMO.
We have the same Motorola one as Brie. We love it. I'm watching DD sleep on it right now. Oh, and it also rotates frequencies and pairs to your specific camera(s), so it won't show up on your neighbor's monitor.
