## Description

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

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.
Review: This Product Works Great! - One of my window security alarm sensors got damaged, so I browsed on-line and decided to go with this brand. 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.
