smoke alarms

by Ralph C -

Four out of the five alarms that I purchased were perfectly easy to install. One had a battery drawer that would not close and required a lot of force which probably will be a problem when I try to change batteries in the future. If I had purchased locally at store I would have returned it for a new one but too much trouble mailing back for replacement.
