I can assure you that as a run-of-the-mill customer, I will likely never check a UL code. I don't know if you get your casings from the same place, putting your own electronics inside, but I feel that if you want to trade on your identity as a purveyor of quality products you're going to have to look at least a little different from bad products. To borrow and twist a line from Seinfeld, "Adjacent to trash, is trash."

I did make the mistake, though, so sorry about that.
