Great! I wore these for 3 months and then took them out and they are still as good as new! I a planning to have them put in again in a month or too after a break. They look proffessionally fininshed and never tangle. The twists did not unravel. VERY thick though can only put them up in a high ponytail but you get a beautiful full and layered effect. I needed 6 packs to do a full head, and they only just covered my head but I have a lot of thick unrelaxed afro hair. If you have fine hair you would need less for sure. Well worth the investment!
