Easy to install and works well. 8 only used one in the set of two so far, but the new one works with my older wired alarm as well.

If they are reliable and work with my existing wiring.
The alarms were exactly like the ones I had, they were super easy to install. Just be prepared to replace the included batteries, mine went dead two days after installation.
