Asitis NutritionAS-IT-IS Shaker Bottle - 470ml, Black Protein Shaker for Gym

What is the use of blender ball,, andif the scoop size is smaller then product is perfect.

It's a great product no doubt! BUT only when used with cold water or milk. It tends to leak when shaken with warm milk (or water if you use warm water). I used warm milk for my protein shakes due to my diet but quickly realized that using the product to shake with warm milk is a bad idea since it leaks all over. HOWEVER there is no such problem with cold milk/water and hence it is definitely leak proof. The best thing about the product is the little ball that comes with it, the ball easily helps to break down the protein powder and mix it well with the water/milk. Great material quality and quick and easy to clean too! Just make sure that if you use warm milk to drink, let it cool down before shaking.

I was skeptical when I was ordering as many has said about leaking. But when I got it, came to know that this is a very good quality portable shaker for a very good price. It is well build, the cover has a gasket inside so its sealed properly, very easy to use and easy to wash. What I like the most is quite handy in size like how I wanted and the price is very reasonable.Just wanted to share my thoughts as there are many misleading reviews.

I'am writing this review after using this product for more than 20 days.The good side of the product is that the material is of good quality, easy to clean and sleek design helps in good look and Easy to carry.Even thou in general the product is good after a couple of days use it tends to leak the contents, I'm yet to figure out why it is happening.So in my opinion if you are looking for a shaker that doesn't leak the contents then definitely don't buy this product.
