Great blender bottle, love this smaller size. Only negative is the cap is like nearly impossible to open sometimes lol. The blender ball mixes much more efficiently than many other models.

Beyond unimpressed with this product. Will not be purchasing again. It’s very cheap and not durable at all.

Much prefer my contigo bottle. It's so annoying i have to open the bottle and get a fork to manually mix it after mixing it with the ball because the bottom isn't rounded so there are powdery clumps galore.

The pivot point for the lid in the hard plastic top breaks over time, it's because the pivot is stressed when the cap is closed. The drinking part is really difficult to open and click down and it's hard to get the lid lined up.
