Door Stop Alarm

Great product at a great price. $6.99 for 3 is unbeatable deal. Use 9 volt battery, 3 modes sensitivity, on "H" mode you just touch it and it goes off. Quite loud and I highly recommend for all to use as door stopper or alarm. Remember to turn off when not in use so battery will be drain off.

Piece of junk.........

I am a big fan of BudK but this particular item is junk. Good news: It claims to be loud and it definitely is loud! Bad news: It claims that the rubber on the bottom keeps it from sliding---this is untrue. I tried it on all three of my doors and it simply glides across my wood floors (without the alarm going off) whenever the door is opened. It was in my trash can within 20 minutes after I received it! Perhaps it works well on carpeted floors but did not work at all on wood flooring!

Door stop alarm

I purchased two of the Mitaka-Japan Door Stop Alarms. One worked great...the other would only work 1 out of 5 times. I returned the defective alarm and received another one. It works fine. It gives my wife and granddaughter that little extra security when alone.

poor quality

I bought this item and was pretty stoked about it. Unfortunately it only worked a couple of weeks then quit. Changed to a new battery and still doesn't work. Dissatisfied overall.
