Door Stop Alarm Reviewed by on Oct 27, 2018   5 out of 5

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.

EASY TO USE Reviewed by Alec Baturyn on Sep 27, 2017   5 out of 5

I loved it, easy to use and very loud

Piece of junk......... Reviewed by Greg Smith on Dec 24, 2016   1 out of 5

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 Reviewed by Eddie Porter on Jun 16, 2015   4 out of 5

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 Reviewed by Robert on Mar 16, 2015   2 out of 5

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.
