Only just bought these as really didn't want a camera monitor due to worry of others hacking them via bluetooth/wireless etc and of course don't think I can handle seeing any paranormal activity with my baby, but after reading the reviews and seeing long gone are the days of 2 way monitors with no image (and what is about isn't worth paying for as used 3 different ones for my previous babies and can't say I rated them). But I was sold on others reviews regarding how far you can take the monitor, the fact they cant be paired to other devices so no worries of who can hear/see my baby, the sound is clear, can play lullabys (you see where I'm going with this) and of course the price is well worth it. I'm not sure how long the monitor lasts before needing to be charged and my only con so far is the lullaby over powers a y noise from baby so when baby cries it doesn't come through due to the songs (unless I've missed something, normally do being a mombie) but the video and seeing them will let you know they are. Guess another good thing is to be able to a make sure little lady isn't getting any secret visits from her 3 big brothers.
