Read my awr-fix on the DHC. Most can be fixed with a single steel zip tie. (a pack costs maybe $5 so 17¢ each).

The non OEM often have minor fitment problems nothing that a few seconds can't fix but be careful of the spring if not the right size will scrape on the window. (also easy Dremel fix)

When using a knock off, move over the cable if it's in good shape. The knock off cables are not great.
