hello .... I bought a Petzl harness SUPERAVANTI C12 16 (3 342540 089037) 2011 version the latest from a friend ... after I noticed there is a seam that decompose / not good .. I can send the photo as evidence that quality standards are not baik.kenapa like this can happen when an existing license of ISO 9001 quality management system .. (seals still in place and yet I use) is it still safe if I use it? thank you Email: yosepdr15@yahoo.com
