Note: purchased wig to do Moka Akashiya cosplay (Rosario + Vampire)
The quality is fantastic: looks and feels like real hair.  Does tangle unbelievably, invest in a wig comb (4 bucks here in the Bronx).  I cut mine to be about 10 inches shorter than it really is and gave it a straight cut because it had a long taper cut to it and looked scraggly because of that.  The straight chop I gave it really added something, and looked a lot less Vampira-y.  Also, cut those bangs!!!  It's not like there are no bangs, they do start you out with some styling, but they covered my face.  Took me all of ten minutes (maybe because I've been cutting my own bangs since I was 15 until I was 20 and finally grew them out lol, but I digress)...
People were asking to take my picture left and right at Comic Con 2012, saying my costume was dead-on.  Made my new fiance very happy, also because he became my fiance there since it's where he proposed!  It's a good luck wig too!!!
