I received them in the mail today. I like them, put them on (kept them on the inside instead of the outside as they replaced the spacers that were already there. Adjusted them and tightened down the axle nuts. Chain tension right at 1/2" slack and it lines up where it should.

The one's I bought were the same one's only black. Black versions have the Origin 8 logo on them. They also fit the axles perfectly and slid into the track ends snugly. I recommend the product for track frames that don't have the hex screw chain tensioners designed into the track ends as part of the frame. 5 stars for quality and value.
