Rated 3.8 out of 5 by 6 reviewers.
Rated 4.0 out of 5.0 by Good little door alarm This is a small door alarm that hangs on door knob. It goes off when moved. It is pretty loud and also has an option for chime instead of alarm. When turned on you get 10 seconds or so to hang it before it sensitizes. However, when you try to turn it off, it is impossible to do so without setting it off. The words along the setting button (chime/off/alarm) are very small and hard to read so you will have to memorize which way to push it to disarm it. The one thing that disappoints is the cover for the batteries has little plastic guide pieces that bend and break very easily and result in the cover not locking into place. Ours frequently falls off. We may have to tape it shut. For the money, I think it is a pretty good product. February 17, 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 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
