Review on Wsdcam Door And Window Alarm For Home Wireless Alarm Security System Magnetic Alarm Sensor Close Door Reminder Loud 110 DB, 4-In-1 Mode Window Alarms 10 Pack by Cori Nance

Great lille devices and amazing price for 10 pack with batteries. 4 different modes are nice feature. Installation was easy. I recommend placing it at the bottom of the window which will make easier when it comes to turning on/off the units, changing the modes or batteries.Some reviewers said a few of them were defective so I checked mine as soon as receiving, luckily all were in perfect working condition.Quick note as I was installing on one of the windows upstairs, I'd noticed it was unlocked for a quite period of time (I do remember the last time I opened was a few months ago). It's right above the roof, which could have given easy access for theives. This product already saved me!
