Rated 5.0 out of 5.0 by Backdoor alarm This is perfect if you want to protect your back door. The alarm is very loud and we are keeping the chimes on for now while we are in the house, but when we go out of the house, we set it to alarm. The alarm is extremely loud, but thankfully goes off after 20 seconds, so that's good, because it will chase the "would be" intruder away, and you won't be getting calls from your neighbors, telling you to come home to turn it off. When we are home, the chime alerts us if someone is at the door and it is not as frightening as the alarm. May 5, 2015
Rated 1.0 out of 5.0 by Don't Waste Your Money I purchased this for my elderly worked great for the first 2 weeks. Then it started going off on its own...which is odd because the door it was on didn't catch any wind or anything that would cause it had a mind of its own. Because my mom doesn't walk fast any longer, it was hard for her to rush over and shut the loud alarm it got tossed in a drawer and will probably stay there. Once it started to malfunction, my mom didn't trust it anymore. July 7, 2015
Rated 1.0 out of 5.0 by Terrible Alarm Door Guard sounds loud alarm every time there is thunder. It is very annoying. Would like to return item. July 21, 2015

Rated 4.0 out of 5.0 by Super sensitive We live near a well traveled highway which is frequented by heavy trucks. The vibration from a truck set the alarm off. During a storm, a tree limb fell on our porch setting an alarm off. Other than that, if you have a steady hand and a steady door, they're a good value. We intend to take one with us on vacation. The alarm has 2 settings: a high shrill and a door bell type. September 2, 2014
Rated 5.0 out of 5.0 by Works great as advertised Ideal for temporary door alarm for when you stay in a Hotel or motel and for use around the house. It also works on camping trailer or motor home door. May 6, 2014
Rated 4.0 out of 5.0 by No problems purchase Product works well, purchase and pick up was easy. June 9, 2015
Rated 4.0 out of 5.0 by Simple to operate and fits well on our doors. Was not sure at first to the sensitivity of the alarm but has worked out well and definitely the alarm gets your attention. The rotating sounds are very effective to both alert you and I think in scaring someone. We liked it so well we bought 5 more for our family. April 8, 2014
