They did a great job eliminating the noise from having a loose belt. My only problem is that my rearview mirror fell apart on the way home. Of course, I can't prove anyone tried to adjust the mirror while it was there, but I didn't have any problem with it before. Trust me, I'm not blaming your company.....just stating what happened after I left your place. I wasn't going to even mention it, but my daughter thought you might want to know, so I answered your survey.
