I love the look and functionality of this bag. I have only been using it for a couple of weeks and have already received so many compliments. I have used it both as a diaper bag and a pump bag for work. When I take it to the office, it looks professional and does not scream breast pump bag. It has space for everything I need to take with me to work. It fits my Spectra S2 pump, pump parts, bottles, cooler, pump wipes, laptop, notepad, water bottle, keys, phone, wallet, makeup, and lunch.The two side pockets are insolated, which is excellent if I don't want to bring along my cooler bag, and they fold away with a button when I am not using them.. I can see myself using this bag even after my baby is grown, and I no longer pump or need a diaper bag. I order another cheaper bag on Amazon, and the quality of this bag is not even comparable. I wish I wouldn't have wasted my money and just ordered this bag. If I could say one negative, I wish it had a key clip. I will update my review if anything changes.
