Purchased this as a affordable baby monitor for use at my house when my niece comes to visit. Didn't want to break the bank and for under $20 (at the time) figured couldn't go wrong, and if it didn't work well or broke no big deal.Well, we've had a few several week visits now where this things gotten a decent amount of mileage, and for our purposes it works great! Obviously we didn't care about having a video feed, just to hear if the baby wakes up/cries. Some quick pros/cons;Pros:- Battery life is good, better than expected. After several weeks of use (say six) finally had to change the batteries (2x AAA).- The receiver also has an AC adaptor for when we're around a power outlet or feel like plugging it in- Range is good. 4,000+ sq ft house and it works from upstairs bedroom down to the (underground) basement, and all throughout the property (haven't tried walking up the street with it, but the range is more than sufficient).- REALLY easy to set up. Plug in the main unit. Put batteries or plug in the receiver. Turn them both on and they automatically pair, done. Idiot proof.Cons:- Audio quality isn't amazing (with caveat, noted below).So, really the only con of this unit for the purposes of having a very affordable audio monitor for the baby is that the audio quality isn't spectacular. That isn't to say that you can't clearly hear when the baby cries, you certainly can, so it's more than adequate. That said, if someone was having a conversation in the room you might not be able to clearly make it out, but that's not really the point of the unit; it's not a walkie-talkie.In summary, this unit far exceeded my expectations. If you're looking for a cheap baby monitor, or really just care about being able to have an audio monitor, you really can't go wrong with this unit. Sure, there are some great HD video monitors out there where you can record videos and cute moments and stuff like that, and one of those may be the unit for you if that's what you're looking for, but for just monitoring a crying baby, this is perfectly adequate.
