Door Chime, Wireless Door Alarm Contact Sensor with 58 ringtones Selectable and Mute Mode, Visible Alert with LED Indicator, Door Sensor + Receiverr Door Alarm (1 Receiver + 1 Sensor)

Very, very easy to install and set up. I love it!! Loud enough but not too loud to let me know when my door is opened. I love that it has so many different chimes to choose from. Great product and well worth the money especially for safety reasons. The video on how to set it up was a plus. A definite recommendation.

Love it, it has different sound and volume leves.

Worked great for a few weeks and but now no matter what ringtone I choose, the system uses the default doorbell wring when the sensors initiate the sound. Frustrating.---------------------------UPDATE: I wasn't following the instructions correctly. I just needed to re-pair the ringtone to the sensors by holding down the volume button for 5 seconds and then separating the sensors within 5 seconds. The downside is that if you already have the sensors installed somewhere that isn't close to the receiver, then you will need another person to separate the sensors after you select your new ringtone. (hence the 4 stars)

We use it at our little shop...easy to install, setup and choose the tune. Great buy!

This alarm is the best I have ever seen. I have bought 2 other alarm, and they did not work after a few days. Can not believe the quality for so little Money !! Buy this, you wont be sorry !!
