I got this mostly for the small bpa free bottles. They are a good size for tossing into my backpack or purse when I'm walking. Plus they don't leak.
The belt is very nice and holds the water bottles too so that is really perfect for a jogger, walker, or runner. It has a couple of zip pockets for money, phone, and a built in earphone hole. It's not junk. Everything is very good quality.
I like to hook it to my homemade grocery cart for a walk to the store and keep my credit card and keys and the water bottles.
