I recently ordered some Perfect Fits from Ed and Dawn. Two days ago, when I went to turn some, I discovered that the chrome finish ones had two upper barrel tubes in the package and no lower barrel (size O) tubes. I called that afternoon, and Ed picked up, and I was able to explain the situation to him. Five complete sets of tubes were waiting for me in mailbox in today at noon, less than 48 hours later. Just awesome customer service. Thank you,Ed and Dawn, from a very happy and repeating customer. If any one needs PF upper barrel tubes, I have spares.
