I've taken every Warmoth neck to a luthier after receiving it. Not because of the frets, but because the nut slots are not cut deep enough. Not everybody here would agree that the pre-cut slots are insufficient, but I've found that it makes a HUGE difference, at least for me. Warmoth does an excellent fretting job, though. Haven't had to get any fret work done on any of my necks, and I've bought 6 of them.
