Adam, thank you for the feedback and for highlighting our team's responsiveness. I'm glad to hear the major repair resolved the concern. I would ask however, even as we receive glowing praise, we earned a less than excellent rating. Is there something we an do to improve or address something? If anything comes up, you're welcome to reach out to me directly. Best, Christian Stark Customer Relations Manager christian.stark@koons.com 410-931-8600 Ext. 27145
