Product review (5 stars): Seems like good quality and dropped right in.
Went right in in about 1 minute.  Taking the washer apart took 10 minutes.  Putting it back together took the better part of an hour, but will be quicker next time.  You need a large pair of pliers to get the hose clamps off, but other than that, there is nothing difficult about this.  Water was leaking from the bottom of my daughter's washer, so I diagnosed this was the problem, ordered it on the cell phone, and two days later, I was at her apartment fixing it.  Other reviews have stated that this doesn't last long and time will tell, I guess, but it seemed like OEM quality.
