This is a well designed product. The whole thing including the pockets feels pretty robust and when rolled up is secure. The pockets themselves are good for cables up to 5 metres. I have a couple of longer cables and they're fine too, just makes the rolled up bag a little misshaped but that's OK. I'm not sure how many longer cables it could take - I don't know but I suspect if every pocket has a 6 metre plus cable, because they are all going to stick out the top of the pockets, it may be difficult to roll up. I would definitely buy this bag again and recommend it provided you don't have a whole collection of very long cables
