I have had two Harley Benton bass guitars, a 5 string fretless, and a 5 string PJ combo, and they both shit the bed and ceased to work in under a year of light usage, both times it was cheap electronics (the pickups).
That being said I have many friends with Harley Benton instruments and amps and they all work fine still, I just got unlucky. Of course, cheap parts are cheap parts and will be more liable to fail than better ones. It is still a lot better than it used to be.
