Review on Aleph DC 1561 Surface Magnetic Contact by Jackie Morales

Impressive magnetic contact. An 8 inch plastic bezel between a point where a wired contact can be made and the nearest point where a magnetic contact will be made which is mounted on a window sash. I doubted such a mount would work reliably, but they are installed on all four windows. The contacts are fairly small, appear to be well made, and contain what appears to be durable 3M double-sided tape. For typical applications installation should be easy and with a small amount of suitable paint the contacts will not be visible. $15 10 quality contact sets also seem more than reasonable if not a steal.
