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.
