Defective.
Defective product. The strap was too small for my head but replacing it is not possible without ripping the hair out. The attachment on one side was in the hair on the front instead of the back of the head. So it would not work even if the stap did fit unless you folded it.  In addition, some of the hair was already falling out. I added a picture of the side which was not defective. I have it two stars but the color matched my hair exactly.
Rating: 2 stars
