Personally, I LOVE this monitor, we purchased the one with two receivers, you don’t need batteries to keep it charged or to plug it in all the time. We have never once had interference of any kind of another baby come screaming through the monitor! I did not want the kind that you could get cool video because we have a smaller, one story home. I have heard the ones for SIDS prevention really doesn’t work if you have a baby that moves, it sets the alarm off putting you in a frenzy. I didn’t let SIDS scare me, in fact, due to reflux, my daughter slept on her belly at 3 weeks.
