I've been using it for about a month. I used it a little when I first bought it, but I gradually started using a backpack as my main bag and forgot about it, so I'm selling the main unit. I'm selling it because I don't plan to use it. Photos 4 and 5: There is some slight discoloration on the metal fittings, but overall, I don't think there's much sign of use. This is a used item. Thank you for your understanding.
