BlenderBottle Pro Series Shaker Bottle, 24-Ounce, Black/Clear

Very nice quality shaker cup. No leaks, lid is very secure, tritan plastic material is high quality. I recommend getting a clear colour since this will help you see if the shaker cup is fully clean. I'd buy another one, the higher price is justified over cheaper shaker cups especially if you use a shaker cup frequently.

Ela ser transparente ajuda a limpar, o fundo arredondado faz com que não acumule sujeira no cantinho do fundo que era horrível de limpar em outras coqueteleiras que tinha

This is the latest of 6 blender bottles I purchased under this brand - with previous products fulfilling various needs for their use (e.g. size/capacity, need for a carrying handle, other innovative uses such as cooking, etc.) The leak-proof feature and "compressible" design of the blender ball in their beverage shaker bottles have made this a go-to brand for me. Among the evolving product features through the years, the round bottom feature on this particular product has been a huge step forward from the earlier versions. Without affecting its volume capacity, the round bottom feature makes it easy to clean and prevents any hard to dissolve "clumping regions" whenever powders need to be dissolved in the contained beverage. I purchased and have used this mainly for travel as an attachable beverage bottle, thanks to its handle and leak proof design. This particular unit I got occasionally leaks depending on how the cap is screwed on, but since I'm currently on overseas travel (unable to replace/return) and had never had this problem with their earlier beverage bottles, I'm willing to believe that this is just an isolated imperfection with this unit.

Works great when making my protein shakes.

Very Easy to use, and clean. I use it for protein after my swim workout and it shakes and works well
