Well, it's only been a few days, but they feel fine. There were a bunch of "they're okay" reviews on E46Fanatics. And dirt cheap -- literally $18 per side plus shipping from Rockauto. There don't appear, though, to be Sensen front struts. They show them in their catalog but I can't find the part number listed as available anywhere. So I doubt I could "match" them with front struts if and when I need to do the fronts.
