Hey guys! I need some help in terms of root lift/volume. I am sick and tired of my Ouidad clips and I just found these roller jaw clamps:

Roller Jaw Clamps

I can't seem to find a good review video on them except this girl who uses only one of them on her hair to demonstrate (2:26):

I would have loved it if she used it all around her head to see how much it would work, you know? Plus the video on the official website is weird... I don't want to twist and clamp my hair like that, yuck!

Has anyone tried these babies before for root lift/volume? Thanks!
