Review on SABRE Wedge Security Alarm Siren by Chris Castro

It's simple, it's effective, but the right function depends on your floor surface. Who doesn't want to finish reading. Conclusion: This is a great and simple solution to prevent people from entering your home while you are at home. However, you will also need to purchase a 9V block battery, you will need a micro-screwdriver to install the battery, and you will need to purchase a simple mounting solution (see below) for slippery floors (such as wood floors, stone, or tile). Package Contents: I bought it on Revain. This time the delivery was a day late. Opening: Alarm packaging is difficult to open. He's completely bloated. It's not very eco-friendly and you'll need a pair of sturdy household scissors to open it. You need to buy a 9V block battery separately. Installation/Operation: First you need to buy an extra 9V battery, if you only find out after the package arrives, it can be quite troublesome as many households will always have AAA or AA batteries at home but not 9V -block batteries. A micro screwdriver is required to install the battery. An ordinary screwdriver won't get far, you'll only damage the screw head. After installing the battery, everything is ready to go. The alarm is loud and works very effectively. But I have a wooden floor and the unit would always slide off when I open the door. The rubber bands on the bottom hold the floor tight enough. So I bought this Scotch Resealable Clear 1 x 3" 2 Kit (RF9730) to keep it firmly on the floor and the door can't move it. ==> This works beautifully. 1) The door is complete and very tightly locked!This deters intruders from entering your home AND 2) You can easily remove the alarm as this tape comes in two pieces, one sticks to the floor and the other to the alarm and you can easily remove the device at any time 2) The alarm will go off safely if the door opens and an intruder can't turn it off - if you attach the alarm to the floor with a latch close enough to the door Final Review: Since the mandatory 9V block battery is missing and requires additional investment for a slippery surface mount solution (depending on your home) unfortunately I can only give 4 stars Once installed correctly it works great The question remains: for how long does the battery last?
