I love the size of these rollers. They are really wide and hold a lot of hair. Also, the thickness of these rollers are nice, too in that they produce lots of volume and body to the hair. The Velcro on them sticks well, and the rollers do not slide down your hair. Of course, the harder you roll them, they will stick even more so and provide you with great height. I am enjoying mine, as they are well worth the price!
