Review on 3 Pack Combination Smoke and Carbon Monoxide Detector: Portable Battery Operated Fire & Co Alarm for Home and Kitchen by Shawn Reiter

A gift is offered in exchange for a review. but never send a gift. They are impossible to get even with the help of Amazon. Therefore there is no product support. As for the product itself. they are very affordable. However, the test instructions do not match the product. None of the 6 alarms I bought ever said "fire" or anything, but they flashed green and went off the first test alarm. I'm curious to see how sensitive they will be to cooking. but so far no problems.
