I bought this monitor a while back, and haven't had any problems with it. I will say that it's extremely tough. As far as the part that you bring along, I have gotten it wet, and it's been dropped numerous times. It's taken quite a beating and still works the same as it did when it was new. It's well worth the reasonable cost. My favorite part of this monitor is that you can choose wether to use it plugged in or not. It charges up quickly and doesn't require batteries. It has the internal battery which holds a charge for a very long time. I haven't had it interfere with other things in my home either which is a plus. I have used monitors in the past that have done this and it's very annoying, so it's nice that this one does not. Another good feature is that both parts have different channels so you could monitor multiple rooms with each monitor and speaker on different channels, and only get one room's sound on each speaker. I think this is a good product and it will definately last a long time. It's not the most fancy baby monitor out there but it works and it works well to hear whats happening in the other room.
