It is was very easy to install. I have tested by burning paper under it and all four smoke detectors worked very well. Sound is very loud. The size of smoke detector is acceptable. Comes with a battery 9volt and the test alarm seems to work and blinks red. It detects only smoke. A very necessary thing in every home / office. A must have device for its ... Read more

It comes with manual and battery which was very useful. It was very easy to install; in-fact I installed it in the few minutes after receiving it. I also tested by burning paper under it and it worked. Sound is adequate. It is smaller than what I thought. I have seen similar smoke detectors but in larger size. Sound is ok but i think it would be better ... Read more

- comes with battery
- comes with 2x screws - found it cheaper in my local hardware store
- screws are very low quality

I suspect its just smoke ... Read more

I have checked some local stores, products they are selling are much expensive but look exactly the same. I am guessing it is the same product. 9V battery is strong an easy to find. Battery installation is easy. That is also comes with 2 screws for ... Read more
Price, dependability, battery economy, low battery alarm, good quality. It detects only smoke, not carbon monoxide (see specs). I tested it in a stuffy room with closed fireplace and waved smoldering piece of paper - it reacted on smoke only and it took a minute of waving. Detector raises its sensivity when considerable amount of smoke is around, if ... Read more
