PROs - Lightweight, flexible and easy to use with portable tools.  Really works well with hand drywall sanding tool.

CONs - Contrary to the photo on the amazon website, this hose is not reinforced like the original equipment hose that came with my Bosch 3931 professional vacuum.  It is constructed of a very flimsy flexible plastic which is very easy to pinch.  Once pinched, the hose collapses whenever the hose intake is restricted and further reduces air flow.  It was a waste of money.  I will need to obtain a reinforced hose which does not have this problem.
