Would not buy again

Pros
- this is great to fill with your own drinks - juice and water
- comes in two convenient sizes
- can fill half way, freeze it and fill up the rest for a cold drink that'll last all day

Cons
- when it full and it's squeezed, the drink come out of the spout
- the spout has to be opened all the way for it to work
- the "straw" inside keeps getting lost
- lots of little and difficult to get to crevices, especially straw/drinking mechanism and the part that lifts up, to clean
- if you use it for milk and the containers sits out all day, it makes it especially difficult to clean had to toss one out as it started to smell bad

Would not recommend this. Would prefer drinking bottles with simple openings so that it cleans well.
