Product working well, price good, shipped quickly August 6, 2018
Reviewer: Anonymous Person from CA United States  
I was happy with my purchase.  The units installed quickly, although I prefer the interconnect wiring on some of the old FireX units.  So far no false alarms or anything untoward.

Shipping time was excellent and the price was right.  My only minor beef is that I could really care less that the company is 'owned by firefighters.'  Too often companies and people seem to try to crutch themselves by association with tangential activities.  Who really cares and it even appears pompous to me.  BUT, what did matter was the service and price and these were excellent.  So, yes, I would happily buy from the company again.
