I ordered this because, being left handed, many bags open the wrong way or even upsidedown! This one opens nicely at the top and I can get to everything. I would like it just a little bit bigger as it's a squeeze to get my phone, glasses case, wallet and a reusable shopping bag in. I can get them all in but it's a squeeze. When I'm on holiday I will rearrange my the contents of my wallet to fit in the slots making it a better fit but for odd day use I don't want to empty my wallet.
I only use it when I'm using a back pack to put my immediate items in rather than having to take my back pack off to reach these things. It's nice to know the bag is secure especially when in cities.
