The absolute WORST! Anyone saying otherwise was given free product. First of all, false advertising. They have pictures they took from some other vendor and didn't have the decency to show 4x4 lace. Instead they show 13 x 6 and 13 x 4. They charge the same though...300 400 dollars. Then, it comes with a smell but I wash my units before using so fine. Well, one wash...soft wash and see pictures. They are crooks! DO NOT BUY FROM THEM! By the time I've worn it one week, all the hair is sure to fall out! CROOKS... I plan on reporting them to the bureau.
