Title: Very LOUD alarm set!
Review: As many has said, this alarm set is extremely LOUD!!! Especially the door alarm. I feel much more secure with these alarms at home. The three window alarms will stop alarming if you close the door, so as some customer has said, this could be a drawback. However with such a cheap price, I really cannot complain more. Besides, the door alarm is really effective, and once the alarm is set, it cannot be stopped unless you enter the 4-digit pin. I'm happy with this purchase and hopefully it could guard my apartment.
