Review (4/5): Not great with fine, thin hair. A little difficult to twist.
I have fine, thin hair and was really hoping this would work as a cute ponytail tie for work.
I found that within just a few minutes, my hair started to slide out of the ponytail. Within a couple of hours, it was about 3/4 in and about 1/4 loose. That continued to progress to the day but never got so far as half and half. I just tried to embrace it as a cute "messy" look on casual Friday.
I did have some difficulty with twisting the beads until they were secure. I twisted them two or three times and thought that would be enough. It took more than that to keep them from popping apart. That resulted in it a little difficult to untangle at the end of the day.
I'm giving this item 4 stars as I feel it would perform well in thicker hair with more texture. Twisting it enough to make it secure but not tangled in a knot still might be tricky.
