Works great. Doesn't really hold position if you're just gripping with a clamp, but it's quite picky and I don't think it should detract from that. It's just something you have to circumvent when using it this way. For example, I take a picture of a small flower, hold it by the stem and position it however I like. When I let go, the position changes, so I have to reposition it to compensate for the movement that occurs. Comes with extra clips which was a nice touch.
