Reviews
- Worked well for meReview by Craig
- I got tired of waking up and finding the garage door had been open all night, so I installed two of these several years ago to monitor my garage doors. I placed them at the very edge of each door, close to one another, and tied them into my DSC 1864 with a WS4965 three zone transmitter. Other than some trouble fitting the supplied bracket to my roll up door, I haven't had any trouble with them. (Posted on 5/7/2015)
- Does not hold up wellReview by James
- I've had one of these installed for about three years, and it has fallen apart. The casing has deteriorated into piece of junk, and although the switch still works, it is only a matter of time until it completely falls apart and no longer functions. (Posted on 4/8/2015)
