Product review (4 stars): Actually a very simple easy task even a man can do (!!)
I thought it would be a lot harder than what it ended doing.  I, of course, shut off the water off the two faucets, not an easy task and I actually disconnected the hoses from the washer one at a time.  They had been there for 18 years and they were very secured at both ends.  Once those twisted hosed were free, I reversed the procedure, installing the warm water first since it was below the cold water, tightened it on to the cold water.  Turn both faucets back on ( that should also be replaced but I don't know where the water shut off is), no leak so far. These lines are somewhat reluctant to change shape but I think that as soon as I run a load of clothes, they will loosen up.  Happy with the results. Saved myself a $60.00 plumber's call
