I bought this bag as a replacement for a LowePro bag whose zipper had separated. I am a professional photographer and I like to have a camera with me at all times, and I was taken by the clever design. I do realize that there's no such thing as a perfect bag; however, this one is billed as a combination camera and laptop bag, and while I only peripherally got to use it as a camera bag (meaning there WAS a camera in it), it fails as a usable bag on all counts. I can only imagine that this bag is yet another example of a product that is never once actually USED by the designers. Had MOSISO bothered to field-test this bag, the flaws would have made themselves known early enough on to be able to be rectified before putting this thing on sale for such a premium price.First, the hook-and-loop strips that hold the separator panel between the upper and lower sections of the bag are thin and FAR less than is useful to actually hold the panel in place when objects are placed into the main compartment. This panel cannot be prevented from falling into the bottom compartment with any adjustment of the hook-and-loop material, and all items in the upper compartment will end up in the bottom, rendering them inaccessible until the camera bag is removed from the bottom and the items are fished out.Second, the separator panel falling into the lower compartment renders the camera bag in the bottom inaccessible without rearranging the rest of the bag. As such, the camera bag part is only usable when out of the main bag; this is where the disparity of the concept and execution are at odds with each other.Finally, a bag with this concept should be able to hold the weight of the computer AND the camera bag, and after a couple of weeks of regular use as just a bag, the right shoulder strap and the top handle began to separate from the body of the bag, rendering it utterly useless without a major repair. As a point of explanation, the camera in question was not a heavy DSLR, but rather a Voigtlander Vito II and a few rolls of 35mm film in canisters. Hardly a lot of weight.My LowePro bag is nearly fifteen years old, and still structurally sound except for the zipper, which I will replace this weekend as I get rid of this MOSISO travesty. Sadly, I do NOT recommend this bag.
