Bests & Worsts Reviews from Amazon

This alarm had a quick easy setup, i had it up and going in less than five minutes. Followed the instructions which said to switch it to Chime mode to test that you had the keypad and door piece aligned correctly....i did, i was so happy a quick easy setup and an alarm that work for less than $20! So i showed my wife how to work the alarm, she set it and opened the door faster than I had...but to my dismay the alarm didn't register...turns out if you open the door really fast the alarm does not register! I tried this on three doors and got the same result everytime and the alarm was set up correctly. If someone breaks in don't you think there's a chance they may open the door quickly??? Avoid this...you really do get what you pay for and mine is now in the garbage.
