Rated 4.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by GREAT I have a 3 year old that learned how to work the dead bolt. I put this alarm on my door at night and it works awesome. Rather than putting another lock on that the kids can't do, which is dangerous in the case of a fire for instance, I put this alarm on my door. It is simple to use, plenty loud enough, about the same as a smoke alarm, and it's small so you can take it or install it anywhere. I can't say enough about this product, it's great and a very good price too for the peace of mind you get. I just put in a rush order for a second one for my back door! May 14, 2010
Rated 5.0 out of 5.0 by Works well, low cost, compact, not too loud Works well, low cost, compact, not too loud. I didn't want one too loud, and at 95 dcb this is plenty loud enough to wake me. However, if you want it to be heard by others in a hotel/house, a 110-120 dcb one should be better. October 9, 2012
Rated 4.0 out of 5.0 by Excellent value for price paid This little gem is great for what I needed. My mom wanted to feel more secure in her senior complex since master keys exist. Yes, she, and we, want someone to be able to enter if she is incapacitated but for her piece of mind, this will warn of all night entries, authorized or not! This alarm is just what she needed. The flashlight is an added bonus! March 23, 2012
