Bests & Worsts Reviews from Amazon

This alarm is loud, easy to install with 3M double sides tape. One thing I wish it also includes would be the chime option, just as a warning of the door open/close. It is, however, easier to have only the alarm option, especially for back door that doesn’t meant to be open and close all that time anyway. I had those one with the chime option, the extra option sometimes are not as convinient for doors that are meant to be shut most of the time. I like it for my back door.
