use it once a week, every week since I got it. I'm very satisfied with this product; it feels durable and the material doesn't feel cheap. It is comfortable and stiff. A rain cover is included for unexpected rain showers in Northern Europe. I have all my cameras (Nikon D3200, GoPro Black Hero 5, Instax mini 9) and all the necessary cables and chargers, a tripod and various things with me. The top compartment for "other stuff" isn't that big, but the amount of items carried can be increased by loosening the top lid thingy, but only by a few notches. I didn't use the side door to get the camera out as I was only using it to transport the stuff from one point to another, for short distances, so I didn't make full use of it. The interior zipper that faces your back tends to open slightly when worn or taken on and off. This could be because mine is so full that it is voluminous and round. Conclusion: In my experience, I am very satisfied with the product. I haven't used it regularly or for long distances, but so far it's been reliable, comfortable and the external design looks good. I would definitely recommend it.
