BlenderBottle Classic Loop Top Shaker Bottle, 20-Ounce, Red/Red

This is the perfect protein shaker. For some reason, other protein shakers tend to be way too big, or tend to leak. In other words, they cant do their ONE job. But this guy is small, sleek, and snaps shut super tight. The whisk ball is just the icing on the cake.

Blender Bottles are the best Ive found, these arent too big so you get enough for a small shake after a workout.

Theres a real big design issue I discovered. The ball is spherical, but the corners of the cup meet perpendicularly with a right angle (like most cups are). This means that the whisk ball will never physically be able to touch the inner corners of the bottle, which can lead to some unmixed powder traps in these corners. If the whisk is square or some other shape, then shaking it enough might be able to disturb the corner build up allowing for a full mix. Yes, this is usually only when I powder first, then liquid. Overall great product, really useful.

Easy to clean and the lid snaps hard enough in place that shaking, or just throwing it in a pack and running around doesnt cause it to spill.

I like my blender bottles. Just wish they were slightly narrower, or had some grip to make it easier to hold. And that the screw top lined up with the ridges where my hand gets the only good grip when drinking from it. I love the loop they added since the older version.

Love this little guy, I mix three different portions water and juice in it , so it holds a three well even though its not super big, it fits in my cup holder nice too.

Seals well and some what easy to clean. Helps to have a little brush to clean threads on cap but a paper towel works also. All around great product. Light and convenient to carry

I love these! Solid little cups, perfect size, and the blender ball really helps. Make sure you have the top all the way on before shaking! Sounds obvious, but make sure you hear the cover click. Sometimes its hard to close, but if I push on one side and sort of roll your palm across to the other side, I can get it every time. I use these for protein shakes (cashew milk + Lean 1), and my husband uses them for his energy drinks (caffeinated powder + water).

I use this shaker for pre workout. It does leak every once and a while but not excessively. It is easy to clean. But everytime you use it, MAKE SURE, you’ve popped the lid down. It sometimes doesn’t pop all the way, and i have slung pre workout all over my truck (don’t recommend)
