I have this as well. Only used it a few times, but I like it.

If I could change one thing it would be the operation of the clamp. When I fasten to my seat post, if the jaws are open enough for the post to pass through, I need to crank them down slightly for the clamp to hold. Then when I loosen the clamp, I have to unscrew the handle a bit to widen the opening.

Not a deal breaker, and don’t see a need to pay more for a better clamp.
