I have used this for 3 years and I still love love love it. The ease of taking it on and off is a plus so you don't have to keep bending over. There is divers inside so that you can make each compartment whatever size you need. You can have a large one for a sandwich, a small one for milk, and a medium for a bottle. I have used this when traveling on a plane for my pumped milk as a cooler which is by far my favorite, I have taken into zoos, water parks, or days out. Its extra storage without bringing a cooler.
