    Cool design, mouth piece doesn’t lock down though

    It’s nice to have options to connect preworkout or protein powder on the go, but the lid for the mouth piece doesn’t click in. It didn’t have any damage or anything, so I don’t know why there’s an issue. This may be just a problem with mine; the bottle is great otherwise and handy, but it’s hard to shake if the top won’t close

    Ocean blue is so pretty!

    I have so many of these pro-stacks. Love the ocean blue color. I had difficulty closing the drink spout, a quick email to customer service got it all figured out!

    Not worth the hassle

    I’ve been dealing with issues with the Blender Bottles since receiving them. They would not let me get a refund which I think is not right. I will not be buying a singlet shaker bottle from BlenderBottle again.
