★★★★★
I first reached out to Roy because we wanted to change our alarm company. He addressed all of our security concerns and sent me a contract. Their contract is well written and not tricky like one of their competitors. When the installation day arrived, Jack and Nick installed our system and they were top-notch. We love our new system – it has a lot of great features and it was a far cry from the old system that we had before. I highly recommend this company – their installation was well done and they did not leave until they knew everything is working and in order.
