I thought I had good luck, but alas, I did not.
I sent them an email requesting help with the part (consew #18025) and received a response indicating that the part had been replaced with another part number. Sure, for $14, I will do it. The catch is that they required a $50 purchase. Sure, I need a knee lift. Done, all $60.
I received the parts yesterday. The "lever" is nothing like a lever. It is another piece that has no resemblance to the screw piece I was expecting. And the knee lever is subpar: the quality of the molding would make any QA line scream their lungs out, not counting the rust that is covering all the pieces.
I immediately sent a reply and I am still waiting for them to contact me back to proceed with a return. I will update this thread when I get some extra info.
