I don't agree with much of that.
First, I read these boards quite a bit and I've done a lot of research for possibly getting my own work done. I've never seen Dr. Feller commit to a yield %. He just says, like most doctors, that it's consistently LOWER than strip. For some people it might be a lot lower, others a little. Judging yield can be a complicated and difficult thing to do.
There's some clinics that hype the FUE technique no question about it. IMO there's also some people who hype the newest donor closure methods for strip. "Practically invisible" are words that are just as misleading and disingenuous as the worst FUE hype.
The reason for getting a HT differs from one individual to the next. But the end result people are hoping for is a cosmetic IMPROVEMENT. For someone who wears their hair shorter, needs a lower number of grafts, or who may be at risk for a widened scar, FUE is not crap, it's possibly the only option. If it were crap, then many top docs wouldn't perform it.
The key is to weigh the pros and cons in the individuals case and be REALISTIC.
