It works flawlessly. It connected instantly, without any difficulties from the floor in between. The sound is more than sufficient for indoor use (the chime notifications are quite practical).

It is not suitable for a siren. It simply makes a continuous beep sound, not even loud even at maximum volume. It is only useful when arming and disarming the alarm because it beeps and you understand that you have armed or disarmed it. It is very expensive for something that my old alarm did without a siren.

    Easy installation, very good signal despite the Ajax base being somewhat far away. The volume is fine since it is intended for an indoor siren.

    Purchased as an indoor alarm siren but in practice it does not function as a proper siren. The sound is very weak and it resembles more of a simple beep rather than a loud alarm that would alert or deter someone.

    Essentially, it only makes sense if someone wants a beep when a sensor is activated (e.g. door or motion). For use as a real alarm siren, it is not sufficient.

    For its price, I consider it a waste of money.

    This review is about a variation of the product

    The fact that I paid €50 for a siren that just goes beep beep, beep, I don't understand that. It's wasted money, of course it's an indoor siren and not an outdoor one, ok, it could have had a different sound and been louder

    + Easy installation and addition to the system. Nice design.

    - I expected a louder sound. It doesn't sound like an alarm, maybe more like a notification; I would say it sounds like the time you set for a reminder in the kitchen while baking it.

    The store 5*.

    The sound is (quite loud) "beep", while it is possible to select the duration of the sound (from a few to several seconds).

    For a house with multiple floors, one siren is not enough if you hope to wake up.

    On the positive side, the size is quite small (about 10x10cm)
