I love my Killer Bee belts. They stay tied better (if you use lockdown) and I like how they drape, versus the sticking up in the air at weird angles you get from other belts.
I had my blue belt for 2.5 years, purple for 2- and they look great the whole time. If you do want that faded / beat to shit look though - it didn't happen with my gi material belt.
I ordered a killer bee for my brown belt- should be coming any day now. Not sure what I'm getting for black belt when the day comes, though.
I always seem to get compliments on them btw.
