We ordered two of these alarms to see if they were what we needed - we are ordering 4 more because they are exactly what we hoped they would be. We spend a lot of time at a cabin in a remote area where we can't expect neighbors or the sheriff to respond quickly nor will traditional monitored alarm systems work. There have been frequent burglaries in the area by both common criminals and by illegals traveling through. My wife is alone occasionally and needs a reliable alarm system to alert her if anyone tries to break in so she will have time to phone for help as well as prepare to defend herself if it doesn't frighten them off. The alarms will also be set when we aren't there and hopefully work as a deterrent.

These alarms are sensitive and loud enough that you wouldn't want to be standing next to them for very long. With the hanging loop that can go over a door knob or be used to hang the alarm on a window latch there is enough flexibility to use them in various ways. The loop can be opened to go around something such as a closed handle or large door knob that the loop can't fit over. The alarm could even be used on items that someone might snatch and run with - although you couldn't have them 'armed' if you were going to move the item. Perhaps on a laptop in a library or coffee shop? A briefcase, suitcase or purse? A motel room door?

They come with 3 AAA batteries. They have a chime setting as well as an alarm setting. Although we have the stick-on type of window alarms on some windows, we will use these on our other windows by hanging them on removable locks that can be screwed onto window frames.

An excellent product for our needs.

I bought this for my elderly father-in-law who wanted to be alerted when someone comes in the back door to his house. It is sensitive and it is surprisingly loud for such a small device. My evaluation is based on initial impressions, I don't know how it will hold up or what the battery life is like. But, I did order a second one for someone else!
******* Edit 4/27/2012
I have to change my evaluation. I have two of the units and they both have the same problem. After the chime has been tripped, the Low Battery light comes on and stays on (thus ensuring that you will indeed have a low battery). I have tried different sets of fresh batteries from different sources and the problem remains. The batteries aren't low and the bright LED constantly on is draining the batteries prematurely.

I bought this for extra security in my apartment. It works very well. My only complaint is it is so sensitive that when my neighbors close their doors too hard, my alarm goes off.

First, my 1 of 2 complaints is that the 'chime' mode is as loud as most any products' alarm mode. Secondly, when you turn it on, it goes through a setup mode in which the chime or alarm (whatever it's set to), will activate to let you know it's working and ready. That may be fine for some people, but I needed something more stealthy. I didn't want the entire building (where I live) to be aware that I was setting an alarm mechanism. I just wanted it to turn on quietly, and if necessary, 'sound' a pleasant doorbell-type 'chime' when activated. It's not what I got. But maybe you won't mind letting everyone in a 100 yard radius know that you just initiated some alarm device.

I really like the alarm,so when it goes off because I slam a door or the neighbors lawn mower rocks the air by the deck door,I may be slightly irritated, but sure know it works. Simple solution is to shut it off during the day. Thunder also will set it off, but I bought it because I hoped it would be sensitive, and it sure is!!!

I am very pleased with this product. It works well and makes me feel much safer. It is very sensitive and works just the way I expected it to work. I would recommend this alarm.

It worked at first, but as soon as the batteries needed changing the weak soldiering broke. For the price I should not be surprised. Good idea, extremely poor execution.
