      Excellent quality

      I needed to replace several door sensors in my home. These sensors were the same type that came with the original security system. My entire home is now back to 100% coverage.

      Great Deal on multiple Sensors.

      Great product. These will be used to replace outdated door/window sensors. Reason is that the battery in my current sensors only are lasting a week or so. These new sensors have dual batteries. The price was perfect. Had I ordered from my current monitoring company I would have paid 3 times as much. These did come from Canada and took a little longer to get here but well worth the wait . Note: you will.need to make sure they are compatible with your system.

      As expected

      As expected. Needed to add a couple additional sensors and these are the same as the ones I ordered with my smart home system. Great price/value.

      good quality and good value

      good quality and good value only issue was range not as good as other sensors I use . I have a long 3000 sq ft house so might not be an issue for others.
