Left the Gen I magnet
I had a Gen I door switch that wouldn't connect (6 yrs of use) and replaced it with a Gen II. The Gen II magnet is smalled than the Gen I and I had in-laid the Gen I piece so I left it and used the Gen II sensor. Now works well.

Nice device for doors and windows
I bought this to alarm an outdoor shed. Super simple to add to the alarm system. Seems very responsive and notifications are instant. We'll see how long the batteries last but the range is excellent. Seems good quality.
