Came too early and not as per order rust marks in battery compartment and on cells...package was different and not working

This product was purchased to keep my little escape artist inside the house. We installed locks he can't reach but, since other people go in and out, there's no way to guarantee they stay locked ALL the time. This handy device helps fill the gap by making sure mama knows EVERY time someone goes through the door! It's VERY easy to install -- if you don't have any trim around your door. If you have trim, you'll need to either forego the alarm or cut into the trim to make a space, because this needs to sit flush. But assuming you have the space for it, just make sure the area is clean and dry and stick it on with the (included) adhesive foam strips. It comes with batteries already installed; you'll just need to remove the piece of plastic preventing them from making contact so they don't burn out prior to purchase. They are, however, some weird button batteries, so when it's time to replace them, they can't be replaced with a trusty AAA. The overall device -- both pieces -- is a little smaller than I had anticipated. I'd say it's a little smaller than two side-by-side boxes of matches. It has three settings: off, alarm, and chime. Off is pretty self-explanatory. I assume if it's set to alarm, it will go off continuously when the door or window is opened. We keep it set on chime, so it goes off once every time the door is opened. It makes a very loud, obnoxious digital chiming sound; you've probably heard it if you've ever been in a store that announces your presence with an electronic chime. It isn't a very pleasant sound if you're standing right beside it, but I'm able to hear the downstairs door from upstairs, so there are benefits to its being as loud as it is. I wish it were designed to use a AAA battery, because the button batteries are exceptionally hazardous around children, but I have no complaints about the alarm's functionality.

This alarm is the best way to add some security to your home without breaking the bank. I ordered two for my front and back door. It comes with everything you need to install the alarms. The adhesive is strong enough to stay glued on the surface, whether it is the moulding or the door itself. The first few times, i had to readjust the positioning and it was still able to stick securely. The sound of the alarm is loud enough to alert neighbors. It can scare pets, so that should be a consideration when purchasing. I either leave the mode either off or Alarm. The Chime sound is not as loud but can still scare pets. I believe this is a great solution for anyone on a budget, especially those renting. Overall, i would recommend this product for those who want something simple that still gets the job done.

Installed on back sliding glass patio door for kids as the pool is out there. Extra security system. Super loud and easy to install.

It works and it’s loud. I just wish it had a more pleasant sound.

Both of my daughters have these in their home and they sleep much easier at night, knowing that they are more secure.
