I love this backpack! I carry around my 16” MacBook pro, 11” iPad Pro, and my wallet, and I always feel so much more at ease knowing that the safety features protect my things, and if I’m sitting down, I can lock it to the chair or table, so I don’t have to worry about someone grabbing it.
There’s also lots of room. It easily fits my MacBook, iPad, many power cords, pencil cases, a couple of sketchbooks or notebooks, and a lunch bag, and then there are still the front pockets and water bottle pockets. It's very durable (as it should be as an anti-theft bag), and I never feel like I'm loading it too heavy for the material.
I will also mention I’m 5”, and it fits very well, especially for being a larger backpack. I do have the straps as short as they go, I wouldn’t want it any longer, but it’s very comfortable on me at that setting. I use the bag mainly for school, so it gets a lot of use. I highly recommend this bag.
