Rated 4.7 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Easy to 'install', great loud sound, slim I bought these to replace existing alarms on our windows and I really like the dark color, slim design and the sound is good and loud. Just what was needed in an alarm. I also like the switch; it's on or off only, nothing fancy. Easy to attach, peel-back tape; it's easier than removing the product from the packaging (why, manufacturers, why??)! And it uses standard batteries, not 'button' ones. Great product & price.

Rated 5.0 out of 5.0 by Very easy to set up and loud So far it has been working great! It is SUPER easy to set up, loud enough to scare someone or at least to make him/her change their mind about entering into my apartment. I placed it on the window where I have the fire scape. It is a very inexpensive way to feel a bit safer in NYC. November 4, 2014
Rated 4.0 out of 5.0 by Very VERY loud! Definitely does what it needs to do, so well that I had to put signs up on both signs of the door warning people that the door had an alarm. Didn't need anyone scaring themselves half to death not expecting it. My coworker and I definitely know that someone has come in the door now. March 11, 2014
Rated 4.0 out of 5.0 by Good value & easy installation I like the use of AAA batteries, as I always have these on hand. The Doberman web site lists the product as a few dollars cheaper than Home Depot's price, but not sure where else to purchase it without paying for shipping. It was very easy to install, but the alarm should be louder. The packaging says it is 100db but the instructions inside say 90db. I would have preferred 110 db. March 25, 2014
Rated 5.0 out of 5.0 by Overall Amazing!! I live in an apartment building that has good security as far as locks but I felt I needed something more, preferably something with sound that could alert me when I was many rooms away from the main door. After perusing this site I settled on this product which seemed simple yet efficient; also it has a great price. Several days after ordering the product I received it earlier than expected and was thrilled that installation was so easy a child could do it. It worked immediately upon installation and I began to test the sound quality. I was thrilled to find that I could hear the alarm from all the rooms in my home even though they are far from the main door, even with the doors closed. This is the exact security I was looking for. My family & I feel safer and happier. Highly recommend this!! May 11, 2011
