Customer ReviewsWrite a review
I use it every day and no problems at all. I like the design and it’s easy to clean.
I have been using this for my daily snacks - the pill tray is handy, everything is in one container, not multiple!
I have loved every Blender bottle I have - and I have quite a few.
These are pretty neat... you can carry your entire snack/pill/protein collection, for a full day at the gym; or you can use it for a complete compact lunch, when hiking.
So much space for pills, snacky snacks, and my protein powder
