The product arrived two days after I placed my order. It was easy to install. It took me about ten minutes. It could have taken me less time if the sensors were little bit narrower. The product came in ten pieces, and I only needed one, so I have nine pieces left. It's been a week since I replaced my damaged sensor with new one, and it seems to work properly. I would recommend this product. Review: Security system back up and running - Quick delivery, little beefier than my old sensors. Liked the leads that can give you a little more working room on a retrofit. Comes with both screws and good quality 3m foam tape to adhere. Replaced some old beat up sensors, now all zones working. ## Features - Gufastore 10pcs Surface Mount Alarm 10W 100V 0.5A in Max Magnetic Contact Ideal for Door Window Security with Lead Wire and 3M Adhesive Paper - 【Reed Switch】When the contact magnetic is near, the switch is close , current will run through it ; When the contact magnet is away , the switch is open ,no current could run through . - 【No External Power Needed】 Connect to wired alarm control panel, GND (Positive) Connect with NC(Negative) ports directly which make signal stability and no trouble for the battery. - 【Install Distance】 ：Gap between 2 pieces more than 15mm, less than 25mm.White color make home great and beautiful.
