Very caring! August 17, 2015
Reviewer: Anonymous Person from Lakewood, NJ United States  
Chris was very caring and took the time out to discuss with me the best options for my home.
Delivered fast and smoke alarms had a fresh manufactures date, meaning they didn't sit in a warehouse for long time before shipped.
