The package came in the mail quickly and the system was easy to "install." It was really a matter of plugging in the base and sticking on the the sensors. It was fine for about a week, and then the sensors started falling off. I had extra adhesives, so I put them back up a few times, but in the end they spent more time on the floor than on the doors/walls. The motion detector did stick well. Additionally, the sound of the standard alarm when triggered is not very loud. In order to get a louder alarm you have to purchase it separately. The price is right, but if the equipment doesn't stick then it doesn't do much good. For $250 I was hoping for better. To be fair, I did get an email from the company asking for feedback. I will be sharing my experience with them as well. It seems like it would be an easy fix.
