My matrix needed replacing and within 24 hours of my calling ADS for help Steve had visited to review the existing system. The next day he and Nick replaced the old matrix with the new 4x4 (4K) Blustream matrix, receivers, etc, he'd discussed with me.
I'm delighted with the results and the totally professional, prompt and efficient service throughout. The ADS price was very competitive and I am confident in their assurance that, in the (unlikely) event the system needs attention, ADS will visit within 24 hours. I couldn't recommend Steve and ADS more highly.
