I have 2x 7ft long fiber jumpers with my live kit, and I had one get yanked a few weeks ago when my vest had a sudden gust of gravity. The repair was slightly delayed, probably an oversight on my part since I didn't send them my tracking number or indication of when it would arrive, followed by a mammoth winter storm. Anyway, Zak jumped right on the case, got my cable repaired and fixed up, and shipping it back to me today!
Very happy buyer, will probably buy another fiber adapter from them again soon (backups for my backups).
2 years, coming up on 360+ shows taped at Warner Bros, and the cables have held up fantastically well!
