I've had two short visits from MiR Audio Video. Both times they came in and did some troubleshooting, found the problem, and fixed it. They are very knowledgeable and efficient. I would call them again if I have another issue. Initially, I asked the hardware provider for names of service technicians in my area. They gave me three choices. I Yelped all three and chose MiR Audio Video. I'm glad I did. They don't seem to be outrageously expensive. Their hourly rate is not quite as much as an attorney but close. I'm glad I don't have to watch the clock ticking as they figure out what the problem is. Five stars for MiR Audio Video.
