    Functional and practical

    What a great idea to have compartments for powders or pills to go along with the bottle. Eliminates extra containers or sandwich bags. I like how it all fits together nicely. Highly recommend.

    First and last Blender Bottle I'll buy

    The flip top was faulty from the first use. Not sure if it's supposed to have a gasket, but mine didn't. Bought it from the Blender Bottle storefront on Amazon. Emailed customer service with screenshot of order number, went through the whole warranty claim process submitting a video of it leaking and an explanation. Got a reply saying it was successfully submitted and then it was denied. Literally just needed a replacement top for the bottle. Rest of the bottle and interlocking containers work fine but poor customer service has tainted this.
