It’s a shaker - works exactly as you’d imagine.  Works very well compared to some of the more basic/cheap ones, in that it doesn’t leak & spray fluids out as it’s being shaken.  The screw down top is nice and positive, and the top cap secured nicely.  Only downside is that one’s never enough, as it’s always in the dishwasher when you need it.  One area for improvement could be a scale on the side of the shaker for fluid measurements (in mls), as found on SiS bottles. 

Received the item within 2 week and excellent packing also the shaker mixes the ingredient well ...does not leak ,easy to use ...... Recommends you too buy this awsome shaker #1 🤙

This shaker has a great mouth piece as it’s not long and bulky like old ones. However the plastic stopper you have to hold on really tight or leaks when you shake. Really poor design so I have had to use old shaker!

The shaker is very good. My main concern was how secure the lid is. So far so good. Good size shaker have bought two.

Inferior product to the previous MyProtein shaker in every way - I can't understand the logic behind the redesign. It has a smaller capacity, thinner materials, leaks very easily, is less durable and the rebranded design looks awful. I am guessing this product is the result of cost cutting to increase profitability. You could have just put your new logo on the previous shaker and you would have retained a good quality product.

Make sure to close the lid tightly to avoid spilling. Other than that, it works nicely

Its an excellent shaker, good material. Just perfect for the job....

Worked well without any leaks during usage. Smashed instantly with a whole at the base once it slip out of my hand accidentally. Expected it to be more durable.

Perfect for the gym  Seals tight and easy clean  And I love the colour 

A stylish and sturdy shaker, I really enjoy using this product!
