I accidentally purchased the wrong size bottle. Took it out of the box and put it back in. I received an email that I was only entitled to a partial refund as I returned the bottle in used condition. I love the bottles but will never buy another one.

Leaks Everywhere

I bought a Blender Bottle at the store the other day but I am so disapointed in this product. Maybe its just my bottle specifically but it leaks everywhere. I have to shake it over the sink and then wrap two napkins around the bottle when I drink from it. No cracks in the bottle, the liquid leaks from all sides of the lid. Its so messy and beyond frustrating.

We are sorry to hear about the leaking you have experienced with your bottle. All of our products are covered under a limited, lifetime warranty. Claims can be submitted for review on our website, or by reaching out to us at

Impressive redesign!

Got a replacement for my previous bottle and noticed the new lid design will seal longer and the new cup mold is easier to clean and mixes powders faster with the blender ball. Color combos are nice too.
