I bought this bag based on the reviews, and overall, it does not disappoint. It is lightweight, holds a LOT of stuff (sneakers, laptop, charger, water, extra layer, wallet, all comfortably inside), and it looks fairly professional, though not high end. The side pockets are great for a waterbottle and mug. The front zip is big enough for odds and ends, and there are two interior pockets for a phone to keep it from falling to the bottom of the bag.
My one issue is that the zipper is annoying. There is a metal frame around the opening with a hinge which you close and then zip shut. Because of this, to get anything out of the bag, you have to take it off, put it down, and then using two hands, unzip the entire bag. Then it takes two hands to hold the top closed and zip it back up. Thus, not super easy access to just grab something out quickly or throw something inside. When my phone is ringing inside my bag, it is not easy to just pull it out. Thus, it's not a great replacement for a purse. But, super ergonomic alternative to a heavy shoulder bag and WAY more comfortable if you walk a lot carrying your laptop.
