So I wasn't expecting the moon and stars for this price, but I was expecting it to work. It's made of heavy duty materials so that's a plus...but I needed this specifically to be able to tighten it down and have it hold the correct size I select. From the moment I pulled it out of the package, the screw that tightens it was cross threaded. It won't tighten down at all. I'm sure it'll make a first class paperweight, but past that, it's uses are limited.
