Input:
I make lunches for my three kids every day and I was so tired of buying and throwing away juice boxes.  These are great.  They are fairly easy to clean, I can put milk, juice, or water that I know is healthy in them, they don't leak when closed, and I'm not adding to landfills.  If you plan to use these a lot, buying a box of replacement straws is a good idea because it's almost impossible to any others that will fit around the spout correctly.
