I wish that I could share the same experience. I have been going back 'n' forth ALL summer with them. All I need are two windflaps. The left one is a 10", the right one is a 8". Drill a 3/8" hole in the corner. I will drill the other mounting holes. The first set came the same size (8") with the mounting holes drilled. I sent them back. It took 2 months to receive the next set. This time they drilled the holes correctly, but the 10" flap was on the right, and the 8" was on the left! I called and told her of the mistake. She promised to make a new set and send them to me. Nothing happened. 2 weeks ago, I called her again. Told her just to send me the two flaps and a bit, I'd drill the holes and send the bit back! She told me that they'd go out that day. I STILL havn't seen anything.
