Define Bottle- Upgraded -Sport Fruit Infused Water Create Your Own Flavored Water (WaterWorks - Recipe Book)

Serves it purpose but quickly tired of keeping fruit around to put in this and it doesn't hold as much water was I would like. Would not. It again.

thought it was hardback

I will not buy another one, I bought 4 and 2 of them started leaking after the 1st washing and I washed as per instructions.

Concept is fabulous but the product itself sucks. After only two uses, the inner coating cracks. They need some serious manufacturing re-design. I wouldn't recommend at this time.
