So I bought this bag to carry stuff for uni. The bag itself is a bit smaller than what you would expect from the images, it's pretty much a laptop bag but it works out since its not too big or small. The material is really nice and the zip feels sturdy. A big plus is the comfy straps, it doesn't pull on your shoulders. The charging port on the side works great, you also get a cable inside the bag to connect with your power bank. This is a great product, better than what you're get in store for the same price range.
