I had my CM15A shoot craps over a week ago, and after jumping threw hoops, they finally determined the unit was defective. By the time they receive my unit and ship me a new one I will probably go a month without the system operating. I find that to be unacceptable, for any company. I rely on a piece of equipment to run this system and it has been down for over a week. Tech support should be available 24/7, so when I have an issue with a piece of equipment on Friday evening, and I can't get things in motion that night or the next day I should not have to wait till Monday for help. I don't believe that they actually read the e-mails sent to them, I sent them a message explaining what happened and what I had tried to remedy the problem, and I would get an e-mail the next (tech support working day) to try something that I had already informed them that I did. Then I would let them know that it didn't work, then I would be asked again to try something that I informed didn't work. Finally, my last Tech Support guy person sent me an e-mail that I am close to get an RMA, but try this and see if it works, I tried it again and sent him an e-mail. Eventually, after a week of doing everything that they want you to do, and reporting back (even though you sent them a message of everything you tried with nothing working, they basically want you to do everything over again.) that it still doesn't work, you will get an RMA. I have dealt with several electronic companies during the years, and X-10 has one of the worst tech support available. I have had hard drives go bad the company will send me an advanced RMA, which is they send me a new one as long as I provide them with a credit card number, and I will not be charged as long as they receive the old hard drive within 90 days of receipt of the new hard drive. I have had a video card with a cooling fan go bad, they wanted the card sent back in order to fix the fan, I told them that if I had to send them the card, then I would go to different company for a graphics card, and would tell everyone I knew that they were a bad company to deal with, since if they wanted the card I would have to buy one to use while the card was being repaired. I asked them to send me a new cooling fan, since it was easy to change, and I would ship them the old cooling fan, two days later I received a new advanced video card for no charge with letter attached asking for my old video card and thanking me for my patience. I had a motherboard stop recognizing IDE devices, I called them up and told them the problem, I had a new motherboard the next day, with no request for the old motherboard. X-10 needs to realize how important customer support is and allocate funds for it, my experience showed me that they do not read the e-mails sent to them and just send automatic replies with suggestions asking for replies, and after receiving several responses of this doesn't work, then an RMA will be issued.
