SECRUI Door Chime 500ft Operating Range 52 Chimes Adjustable Volume with Mute Mode LED Indicators 1 Plug-in Receiver 1 Magnetic Door Alarm Sensor for Home Security & Office

Not of much use on the freezer door as it only sounds for a short time and doesn't repeat if the door is accidentally left open....which is why we wanted it.

Easy to install, works great!

La verdad no le tenia mucha fe pero me sorprendió lo uso para mi negocio

Excellent product easily installed I would highly recommend this product. My husband has dementia so now if any door leading to outside opens the chimes chime instantly. I know longer worry about him going outside without me. Great price as well

works perfectly only reason I did not give it 5 stars was that directions were not very clear on set up after using up the 2 strips of double sided tape I finally figured it out and used modified command strips to install it. receiver was easy to set up and is loud enough to notify m 86 yo mother when the door opens with out being overly loud and annoying.

set up at the front door of my shop. first day i was getting a lot of false alarms, but ever sense it works great.
