I purchased this monitor at Target last summer, for use in my baby's room during her naps and bedtime. When the monitor works, it performs very well. Although I couldn't quite hear baby breathing at night (new mom paranoia!) I felt secure in knowing that if there was noise in the baby's room, I'd hear it.
Unfortunately, after three months of daily use, the monitor stopped turning on when I attempted to do so with the switch. After switching it back of and on again multiple times, it would eventually work. A couple weeks after this problem began, the monitor took more and more "coaxing" to get it to work, so we exchanged it at Target for the same model.
This second monitor is on its 7th month. So far, so good - although we have had to fiddle with turning it on at least twice in the past 4-6 weeks and I am worried that this is indicative of a future breakdown like before. Other than this issue, the monitor performs well - but when this one dies, I will read reviews and consider spending a little more for something that will last.
