There are a few pro's and cons of this product but overall a wonderful product.
A pro would be the quick and effortless twists that are created. Those with thick hair are able to make twists easier. It is battery operated and portable.
The cons would be that those with layered hair will definitely have a difficult time creating neat twists and the clasps don't hold alot of hair therefore only creating small twists. The hair can often get tangled, especially thick hair.
However this product is definitely at a great price and can create effortless hairstyles especially throughout the summer rush.
