A lot of play in the mechanism. Not very accurate. No thumb roller. Nice little case though.

Upon receipt I noticed package had been cut open. I noticed that it has no thumb roller to easily expand it to a specific size. You have to slide it back and forth. Takes too much time to use it accurately. That explained the opened package. It had been returned. Its a cheap tool, as reflected in the price. I hesitate to return it because then Ill be out postage with nothing to show for it.
