So far so good.  I had a unit that had been pieced together, was a pain to start, and noisy when it was running.  I replaced it with the 5HP unit and could not be happier.  I mounted the control box, wired it all in, and turned it on.  I actually had to turn a fan off to hear the unit running because it was so quiet.  I have only used it for about 45 minutes total run time but the ease of starting and quietness of operation are very much appreciated.
