Review on SABRE Wedge Security Alarm Siren by Derick Johns

I need this because I often have to leave the door open when cooking or roasting to let air in and out through the apartment window. My loft apartment has no ventilation other than the back window and front door, and they are on opposite ends of the apartment (60 feet apart). The problem is that both have to be open to the air, in which case there is a risk of someone entering the premises without me being constantly guarded. Being able to leave the door ajar to ensure it doesn't open again is a necessary measure. Security and the fact that the doorstop comes with an alarm is great. I can be on the other end of a device running in my store and hear if anyone is trying to get in. Anyway, enough about me, watch the video :) I hope it helps you make the right purchase decision.
