I had the Bosch solution 16 plus installed by Matison Security and am extremely happy with the service and results. I live in the northern suburbs and Richard showed no hesitation in coming out and completing the job. He is extremely professional, punctual and shows a degree of respect for his work and your property that i find missing in most service personnel. He also came back to install a central splitter to the same exacting standards that he and his company have come to represent. I would give more stars in this review, but 5 is the maximum at this point in time. I also have no hesitation in giving my full recommendation.
