the bag be really good look . I would say it be sturdy and it would protect you jumper cable or any other tool you may want to put in . for my surprise , as soon as I put my cable inside the bag and try to close the zipper , I notice that the latter be not able to close the bag at all , as it come with a small opening on the start end , cause the zipper to open again . I be send the bag to change or fix the zipper at a local shop as I think this will be less painfull than return the item , explain and then wait for a replacement -lrb- and then , hope that it come in work condition -rrb- .
