    A great extension for the security system! It definitely amplifies the siren when placed in a good echo-y spot!

    Easy to install, has sticky tape on it so peel off the cover and stick it to a wall or where ever you plan to put it. Follow the procedure to add it to the system which is easy and your all set.

    Easy to Install and works as described. This can be set so loud that anybody, including people who live with you, who remain in the house when this goes off are either deaf, disabled or are a '60 watt bulb in a 120 watt world.'

    Easy to install and works as intended. I was able to hear the beeps on opening and closing a door - the keypads did not beep loud enough, but this allowed me to put it in a better location and adjust the volumn. Highly recommended.

    I bought this with the panic button and together they don't disappoint. The siren is loud and the panic button is isn't. Simplisafe calls within seconds. A must buy if you have the updated system.

    This siren is no joke it is loud. It is good to install near a garage door so the neighbors can hear the alarm go off. Most importantly hopefully it does its job too cute the bad people away.

    We needed a way to be able to hear the alarm when we are upstairs in our bedrooms with room air conditioners on. This siren is plenty loud enough.

    The simplisafe catalog says this siren is loud and they weren't joking. You can use this inside or outside and you will try to get away from it.
