I'm so sorry to hear that you, too, have experienced some issues. As I had previously stated during our e-mail correspondence, I would be happy to personally inspect your systems before they are shipped to you to ensure better regularity of specifications.
I don't see that you have returned any units in the past four years. If you are dissatisfied with the system you receive, it is very helpful if you are able to return it so that we can inspect and rectify the variations in your specifications. Many repairs and adjustments can be done right here in our Pennsylvania office. We want to help and we really want to get it right! Please don't hesitate to let me know how I can best assist you.
