ONe thing i forgot to add, I only really care about bleached knots at the front hairline. my density is thick enough that the knots on the base dont really matter, and im assuming these knots are much bigger, and probably harder to bleach. People i think become overly fanatical about knots. I was just saying that its possible, But i guess some people in here rather the unit last less time and not be able to see ONE TINY lil knots.

for me as long as the knots are decent at the hairline.. who cares.. who the hell is gonna see them anyway. But factories vary sometimes. I have units perfectly bleached, some not bleached enough.. either way they were all fine for me.
