Best price, plus fast shipping. Will use Bees Lighting again.

smoke alarms

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.

Easy Installation

bought five alarms that all installed easily. hopefully, I'll never find out just exactly how good they are. But, Kidde is a well-respected name for all things related to fire prevention/warning

Great smoke detectors!

I am very pleased with my purchase! Great smoke detectors and the price from Bees was much cheaper then buying them from a local box store. I would highly recommend and consider purchasing from bees again for any future needs that I may have.
