I called HDTVSupply.com because I saw they had a 6x6 HDMI matrix device. I purchased one from Monoprice and it just didn't work. I called and asked more about the product. The guy who answered was a real nerd. I have no problem with nerds but within 1 minute of talking to him he told me he was an electrical engineer. Ok no problem with that but he must have brought it up 4 more times in our conversation. Again all of this isn't bad. He went on to ask about my setup and native resolutions. He was thorough with his questions to understand my situation. He criticized my choice of cables (they are cheap ones from monoprice I will admit). Then he told me to google "hdmi problems" and I would find 4 million results because of cable size. He went on to talk about the 19 paths in an hdmi cable. He asked if I was going to use a receiver and I said eventually I did plan on it. He told me that was a bad idea. Then he started to say google-ing hdmi problems and I tried to say something and he snapped "You need to let me finish". I should have said thanks anyway but I really wanted to know if I could use his switch. 10 minutes in to the conversation I still didn't have an answer. So as we talked I said I have one more question and I asked about their boosters and he directed me on the website and I said ok one more question and this went on a couple more times as we talked about more things more questions came up. I asked about if the matrix switch doesn't work can I return it and he said yes paused and said but there is a 15% restocking fee to cover the credit card transactions. I was nervous as this is a $2000 device and 15% is not inconsequential! FINALLY I said ok I have one more and he said "Last One". He said something else and I finally said well thanks I appreciate this information and at least it hasn't cost me anything yet. At that point the line went dead. And I thought about it and I said I bet he hung up on me. Well I called back to give them the benefit of the doubt and he didn't answer. I left a message asking the last question bringing back up the receiver and the matrix switch. He had earlier described it as two intersecting 19 lanes of highway with no traffic light. Anyway I called back the next day to see if someone will answer and they don't. So I select the option to place an order. I ask the nice lady if she is an employee or an order take from an outsourced company. She didn't understand so I finally asked if she worked for hdtvsupply. She said she did and I asked her if the man who has a electrical engineering degree is the owner and she informed me that he is. I then let her know I would never buy from there ever and thanked her and wished her a good day. Too bad because their prices aren't bad and their products look nice enough on the website. Customer service from the owner himself was lousy and downright rude. He lost my business.
