Query: This product will kill you

I could not believe the low ratings for this product, so I decided to buy one and test it.It triggered with a small amount of steam. Boiling a quart of water on the stove in an open pot on an electric range top, in a kitchen with the windows open, the alarm would trigger as far as 23 feet away down a residential hall.However, I was unable to cause the alarm to sound with actual smoke. I started with a bic lighter 2 feet under the detector. I moved to newspaper on fire in an open pot. Finally I built a smokey wood fire with green wood, sawdust, leaves, and pine 2x4s in a BBQ in the back yard, and held the smoke detector directly over the fire with tongs.It never sounded.I dropped it in the fire. It melted, and eventually burned. It never sounded.It is my belief that this device should be recalled from the market. It will NOT alert you to a fire in your home. DO NOT PURCHASE IT. If you have purchased one, buy a smoke detector made by another company and throw this unit away.
