Good looking and reasonably priced. Base mounting holes aren’t aligned up-down or left-right with the alarm face, so if mounting on wall, the screw holes are at an angle you have to correct for.
They appear to be reasonable smoke detectors but their function remains to be seen as we haven't had them very long.
