They charged us 75% before and 25% upon finishing. Unfortunately we paid him the final installation before fully checking to see if everything worked. In the weeks that followed, we had nothing but problems. I am a pretty tech savvy guy and have fixed most issues on my own, but for the couple of times we really needed them to help fix something, they were nothing but incredibly rude, unresponsive, and dishonest. They wouldn't return phone calls, emails, or texts. The guy that we were dealing with, Paul would never return messages and finally told me to call the office. Their office has some young girl working who knows nothing and actually told me they told her nothing and kept her out of loop. Her main job there is to run credit cards for payment.
Dealing with Paul and and the rest of them was the biggest nightmare. They were only nice when they wanted money, and afterwards did not backup their work or provide any service at all. They would aggravate you beyond hell just to return a phone call. They also charged much more than the competition and sold crappy older model equipment as we found out later. They sold us a Nuvo music player when it was going out circulation as newer models have come out.
If you use them, be very careful and watch over them like a hawk, because their installer will take accessories that come with the new equipment in the manufacturer's box, and even take your old still-working equipment without you permission. They took several of these items like this out of our house when we were not watching.
DO NOT USE THEM!
