Query: Someday.........

I too had high hopes and it seemed to work as expected, but I soon was very disappointed. For some reason it began to lock up and just sit and whine like a siren. I checked the mfg web site and even updated my firmware, that wss not the problem. I called and emailed Tech Support. At first they were concerned but that didn't last long. After a number of emails and one "test" they wanted me to do, they promised to replace the "defective" unit. But, they said it would take a few weeks. It's been a few weeks and not only is my controller not working it's not replaced. Good idea, and maybe someday someone will get this part right.
