Sad as it is to say I am glad there was something wrong with it that you could verify. Wonder how many more who don't have a clue. At least the seller is trying to reach out to buyers about the problem but how many other sellers are there peddling that same part,Hmm.
Just to add to the confusion about these parts: there are 2 "generic" tensioner kits (parts) out there, besides the Honda parts. The Taiwan type is one, the "Made in Japan" label is on the other, and then the Honda parts. I have engines out there, since 2012, with all 3 types (but no problems in any that I know about).
Always remember, when working with the tensioner parts, to make sure of 2 things: first, make sure the bearing inside the larger roller spins effortlessly. Second, make sure the swinging pivot arm that mounts over it, which has a square notch punched out in one position, is slick, smooth, and pivots freely. This seldom happens, even with Honda's parts, because the sheet metal parts deform when punched. The Honda ones appear to be more "tumbled" or "finished" than the others and have less drag at this notch, but still some: file the drag away and make sure the parts move freely. Reason: these are merely splash-oiled by the nearby chain, so their surfaces need to require little oil. The oil holes in the pivot shaft bearing are held upright by the rubber blocks in its ends: if it does now STAY upright, it also will not collect oil. Then it will seize the bearings. Then the rubber parts will be subjected to very high, erratic loads.
