I meant to take pics and forgot. First it's much SMALLER than I thought - you know it "looked bigger in the picture". However this little thing is much louder than the one we were replacing. Upside it uses a standard 9v battery so no weird battery combos. We used this on an metal emergency exit in a retail space that was about 120' from the cash registers. Now everyone can hear if someone tries to slip out that door into the parking lot. It has an internal reed/magnet setup that works like a lego block and can be moved around the inside of the unit to wherever the magnet contact is on the door. My only suggestion - the screws are pretty much for a wood door setup so save a headache and grad some self-tapping metal screws if using on a metal door and/or door jamb. Happy so far but it's only been installed a few days. I would only update this if it dies in the first year based on the price alone.

Exactly what I wanted. Can't buy a better door alarm for this price level. Was easy to install and works perfectly. Lots of adjustable options. Works well for restaurant emergency exit door.
