Review on Steel Tube M12X1 0 Bubble Card by Michael Lightfoot

The product is mediocre but does not leak so it's good. There were lumps of anti-corrosion coating on the threads that had to be cleaned with a file before installation. Without registration it would not be a manual process. The workmanship is sloppy and the metal is softer than the OEM. Despite claiming to be the best, delivery took 4 days. It wouldn't have made much of a difference, other than not being able to finish replacing the brake lines on my car two days longer than expected.
