Yes, and it was also junk. If you look hard enough you will find reviewers who have tested them under varied enough circumstances that they conclude it is no better than any other option. I knew this and tried it anyway. So. I did the research, should have known better and decided to try it out anyway. Silly me.
BTW if you want something that actually works, I found it but be prepared to pay out the nose: Cush Core Bead Bro. Works even better with the $30 companion Bead Dropper lever. Yes thats right $50+ for a solution but I'll be damned if it has not proven totally effective across every tubeless and tubed combination I have worked with. Including some I knew for a fact would be a nightmare. The bead tool (not necessarily the lever but that is nice to have) provided the necessary 3rd hand function to solve every problem I have thrown it at.
