this review title is: missing critical feature read before buying and the content is: this only has one part that rotates once you get the two strands twisted up you have to manually twist it in the opposite direction to twist the two strands together so annoying most all other ones out there have two twist features one for the individual strands and the a reverse for both strands together very disappointed returning.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
