Rated 4 out of 5 by 3 reviewers.
Rated 5 out of 5 by I'm so impressed! I'm so impressed with the product. It's not flimsy! In fact the price I think it's reasonable, I've actually seen it work and I would definitely buy more when the time comes. I recommend it because it's not just a smoke detector it's also an electrical detector. This is actually with the fire marshals recommend that homes have instead of just smoke detectors I did my research. April 24, 2013
Rated 4 out of 5 by Good Value Great for the kitchen. Stopped the false alarms from cooking. Good value for the price. March 5, 2013
Rated 3 out of 5 by closest I could find for hearing impaired was looking for a battery powered photoelectric smoke detector with strobe for hearing impaired tenant, but couldn't find after web search-this only has a small light that turns on with the alarm, but doesn't flash; we'll see if useful/effective May 14, 2011
