Review: Classic Smoke Alarm That Works - Good Features & Value - I bought this to replace an older model (200B) that went bad after ~7 years so decent lifespan. I love the small foot print and there is blinking light that is not obnoxious (you have to look right up into it) you can see at night to know it works in addition to testing. I usually test every season. It comes with a regular 9V battery. I will probably change in a few years. I've bought higher expensive smoke alarms and found they fail so much quicker. Bottom line these are old school and work.
Review: OEM replacement - I got this to replace the OEM smoke detector in my Rockwood Roo 183 2013 camper. The item came in packaged well and with adequate instructions for installation. The OEM one had the same exact mounts as the new one. After installing it I ran a couple of tests on it and it worked perfectly. Also at camp some smoke from our outdoor fire got trapped inside the camper and set the thing off so it was a good test to see how it actually works in real time. I wrote the install date on a sticker I put on the underside of the item so I would know in the future when I replaced it. This one is an exact replacement and I would highly recommend it to others.
