The Manji is a fantastic harp. Each one I've received has been practically perfect out of the box. I love it...but then other days I just like it a lot.
I'm a plastic comb with inset reed plate kinda guy. The PowerDraw, Session Steel, Special 20, Yonberg, and Lee Oskars all have the plastic comb and inset reeds that I like. The Manji is a STYLE of harmonica that I prefer less. So when I say, "I don't play Manji harmonicas very often"...it really is me and not the harmonica with the problem.
The Manjis play very well. You can pretty much bank on that.
