This is an awesome product of high quality. My friend has had this for almost a year now and they still are adhered to his walls and work just as well as they did when he first set them up. My other friend had bought a cheaper brand (which I almost did) and I guess his adhesive strips gave out within a few weeks or so. Easy installation and great customer service. I had received a faulty control box and power supply and within a few hours of me contacting them, they responded and shipped me out new ones. That's how a company should work and I will be recommending this to my friends, family, and fraternity. Thank you!
