Rated 5 out of 5 by from Super Sensitive Door Alarm, Easy to use, very loud The door alarm runs off batteries and are included with alarm. The alarm has a switch on its right hand side for: Chime, Off and Alarm. The chime sounds like a door bell, pleasant and a quick ring (I think its three chimes). Off - self explanatory. The alarm setting sounds for approximately 20 seconds with a serious of loud sounds. It is very loud and my husband, who is hard of hearing, can hear it. The slightest bump of the door, doorknob or frame will set the alarm off. You simply hang it over the doorknob, so no installation is even required. We have had two episodes of a false being high wind pushing on the door and the other thunder. If you want extra security at your door or simply have a family member hard of hearing, this is a great addition. I would have no problem purchasing this item again.

Rated 5 out of 5 by from Excellent product Purchased two for house doors after my elderly father"wandered" in the middle of the night. I am now living with him and if it happens again this alarm will definitely wake me up. Setting it is tricky but once you're used to setting it it can be done without setting it off. I have it set for chime and it's LOUD!

Rated 5 out of 5 by from 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.
