To much crap on your website. When I was filling the info in I kept getting pop-ups for 7% discount, state and city ect. I order parts every day and this is the only site that is this bad.

Purchased replacement smoke detectors for units-needed to stay with the same model/specs. I was able to purchase what was needed and they were delivered in a short time.

Very prompt service, parts received when quoted and an unbeatable price 1/3rd what our alarm company wanted. Allowing us to get a room back online much sooner. we will be using them for all our alarm system needs from now on
