Query: "Extremely Rugged" - NOT

After 6 weeks the casing on the drive broke into three pieces. The cover split along the seam. Had no luck contacting Sandisk for warranty coverage. I used it for a few months longer held together by tape before I got another flash drive (from a different manufacturer) with a retractable USB connector (my favorite feature as I am always loosing caps)
