Avoid if possible. There is no way to contact their business offices directly via phone. Even during business hours, all calls go through a call service that largely runs interference. If you have a billing problem, good luck getting that resolved. We made the mistake of giving them a VISA card to have on file for the quarterly $100 monitoring charge. 3 months ago they charged it five times in a 3 week period ($500 total). They still have not refunded the money and half the time do not return messages (that have to be left with the call center). Have heard other stories from neighbors who wish they had never used their services.
