Details made the difference.
I have been with Security One for about 5 years. I was originally with another alarm company but after listening to a segment of the Clark Howard show I switched to Security One.They had better pricing, a local UL monitoring station, and month to month contract. I have been very happy with them and have had the same service representative all 5 years to assist with the few issues I have had, which is very nice. They are very good about promptly calling and asking if everything is ok and they are also very good at getting things fixed if something ever goes wrong. I feel secure and happy with Security One and plan to use them now and in the future.
