Am completely satisfied with the part. Very good value for money. He has only 12 hours rest time, when he comes, so the compressor is not "the hooves tearing up". But is not as wild as you anyway need a few hours to get the protectors out of every crack. The manufacturers have made the final assembly with all foil. This makes them all the stall under the fixed mounted edges.
I recommend you to edit the cracks with wooden toothpicks until the film is removed.
