Review (3/5): It's ok.
They don't last me more then 3 weeks at a time but I'm able to move them up and reuse them. They are very easy to put on and take off. I don't know how to explain it but the way the top part is made gets very itchy. I only use it for volume so I don't have that many in. I could imagine it would be extremely uncomfortable if I was using them for length and had a whole pack or two on.
