This has been a great investment.  The hose is so much more flexible, lays flat, and seems rugged.  I've been using it while building my basement and have been happy with it thus far.  I assumed it wouldn't twist on itself as much but it still has the characteristic twist when unraveled at least initially.  It is however so much better than the PVC style hose that came with the unit.  I used thread seal paste for the connection points at the ends and no leaks are audible and the system holds pressure during off time.  Overall I am very pleased with the units performance.
