Product review (3 stars): Not Mueller / B&K
The copper tubing appears well made and arrived in good condition.  The tubing even has rubber covers on the end to keep the insides clean.  I was disappointed to open the box and find the tubing to be Hailiang brand instead of the Mueller/B&K brand advertised.  It is part number V-HLR-050-0250 and EAN barcode 8884384090015.
