First, I was excited by ordering this item, because the bags are big and I could fit A4 folders in it. But then, within a month, the inner material started to fall apart. Also the size of the bags made it hard to fit on a bike alloy carrier and the bag edges interfered with the bike chain and wheel. Once it caught the wheel so much that it blocked it and I nearly fell over. That time it was very distressing as I had a child on my bike. I asked the seller if I could get a return for the item and I was sent a formal e-mail with the company's Return Policy stating that I shall pay 25% fee for returning it after 1 month. I do not see a reason why I shall be paying for purchasing a poor-quality item. Not happy at all with this purchase.
