BlenderBottle SportMixer Twist Cap Tritan Grip Shaker Bottle, 28-Ounce, Black

This is a practical size for single serving- also makes it easy to clean! Does not leak.

The bottom of this bottle has a rounded edge so protein and powders don't get stuck there like in older models. Plus the grip and feel is premium.

My son uses these for water bottles at school. I like that the spout doesn’t have a ton of little parts and nooks and crannies that could harbor mold. Simple and basic design that works. No leaks and durable.

Very pleased with this shaker bottlePros: Great size for smaller drinks Textured grip feature works very well and allows bottle to be more comfortably and easily held Twist cap is easy to open and close. It's not a "snap on" cap, it twists to open and close. No leaking. Using a powder mix with milk, all ingredients blend very well, even without using the blender ball Both bottle and top wash easily. I wash by hand but assume it would do well in a dishwasherCons: The ounce measurements on the bottle are almost impossible to see when trying to add liquid to the bottle. It would have been better for these to be shown in a white (contrasting) color The ounce measurement goes up to 10 oz, then there is the textured grip and the next ounce marking seen is 17 oz. If the full bottle is needed, this may be a issue for some.

What I like about this bottle:The rubber 'band' just under the lid makes gripping it effortless. Even if wet from filling.The small drink cap turns to open/close and seals great. No leaks. Same with the fill lid. No leaks.Fits in my Edge cup holder (Yah).The quality is great, keep up the good work!Blending is easy and complete, it mixes my Molk Protein Powder thoroughly.Cleans up easily.I have two blender bottles, this is my favorite.What I do NOT like:(I hate it when people review that there are no cons, however...)I do not have anything negative to add to my review; no, really. In fact I am buying another to have as a spare in case they upgrade the design.
