Okay, the first round didn't work at all. It was printed, but so faded and light it was hard to read. I never thought of returning it until the window was over so I just checked, said it was rubbish and explained. The seller saw the review the next day and immediately responded with a replacement offer. They did it in two days. The new set works perfectly as expected. So the product being replaced loses one star, but the seller's response and actions, even after I waited too long to return it, raised it from an average of three stars "works well" to four. Overall very satisfied with the product and particularly satisfied with the seller.
