I relied on this product for daily use for YEARS. I noticed immediately when I was unable to stock up on the blonde colored ones, and then got as many clear as I could find. Now that my stock is low, I've noticed a formula change. The elastic is too stretchy--which makes them slip out of my hair. Also, the strength isn't as good--which means they break more often, even after you think your hair is secured, and you're just sitting at your desk. Combined, this is a completely unreliable hair tie. You can tell right out of the box, since the elastic twists into a knot soo easy- that they also snag hair to the extreme when removing the ponytail. I will NOT recommend this product, nor will I purchase anymore until I see reviews that indicate goody has returned to the old formula, of reliable, reusable, invisible hair ties. Such a disappointment.
