Really nice back scratchers. I like that they come in six different colors, and you get one of each.
They scratch well. Not too sharp, but not too smooth.
Extended the arm is a little stiff, but that's ok, so they don't extend or open on their own.
I keep one next to me while watching tv, one at the head of my bed, one in the bathroom, and one in my purse. One I shared, and one is extra.
