(MC-AL) Wireless Door Window Open Alert Home Security System Siren/Alarm, Standard Size, White - Set of 4 Nos Sensors

The media could not be loaded. It’s a good security alarm. Compact in size and very easy to install. You just need to remove the adhesive cover tap and just fix it. Keep in mind to put both the items closely otherwise it will not work. So overall a good alarm set to purchase.

Sound is loud, battery backup is also good. Just hope the magnets were bit strong.Good product, does its job well.9 out of 10

Good for the price. does what its supposed to do.

Very very bad quality

I had ordered 4 units. One unit did not contain batteries. The battery compartment has a slide-out clip. Surface of this clip is TOO SMOOTH so it’s not easy to open battery door. The ON/OFF switch should have been recessed/ flush mounted as it is too easy to access now. Overall, good product for its price but there’s chance for improvement.They should consider adding 3 seconds ON Delay while switching ON first time and 10-20 second “delayed siren off”.It will be more effective as the siren will switch ON instantly (when door opened) but will stop only after 10-15 seconds delay (when door/window is closed).

The media could not be loaded. Super sensitive door alarm..Very easy to install..Value for money..Very loud alarm sound..Very easy security measure..Strongly recommend to buy..100% Satisfied with product..

The product is fine. The sound is loud and irritating which is actually good. Except one of them did not work properly. It kept ringing even though the door was closed and the distance between the sensors was very close.

Works only if door and frame are 5-6 mm away but in practical its not the case.
