Verified Purchase(What is this?)
This review is from: BlenderBottle Sportmixer Shaker Cup Water Bottle (Kitchen & Home)
I read in one of the comments that the bottle was hard to open, and it really is! its not apropriate to give to a young child, apart from that, its a really nice and sturdy bottle, either for use in sport mixing or to carry with other types of drinks.
