Very good overall, but the material easily absorbs liquid, and if you have the lid closed it smells strongly. Also, the plastic strainer that attaches to the lid internally is very fragile and needs to be handled carefully when putting on/taking off

It is the only way I managed to mix protein powder well. The other methods, shaking, conventional shaker, mixer, etc., never worked and always left the powder undissolved.

At first, I was impressed with its components.
Good overall, just the extra bottom container doesn't hold up for long, as after 20 uses, the latch doesn't catch well and it's not functional.

Very good for its price, the space for the dust underneath holds about 50 grams and it does not leak, while it is also easily washable

Y.p.e.r.o.cho
I had a difficult protein (in terms of solubility) and this made me dissolve it perfectly. It also has its own container so you can put the solvent and... shake!
I have it now for 2 months and I am very satisfied.
The only negative thing is that it is a bit tricky to clean. It requires thorough rinsing everywhere to remove residues. Not necessarily soap if it is intended for the same purpose, unless needed.
And nice blue color, who says no to blue?

Excellent. The net does the job, there are no leaks and the separate container for the supplement is quite convenient!

Today I tried it for the first time at work.
Amazing. The protein says 30 seconds of shaking, I did it for a minute and there was no clumping or leakage. Easy to rinse.

With a dosimeter on the side to calculate the ml of liquid you want. The bottom part is removable for storing the powder you want to use. All parts of the shaker screw on and fit perfectly, no problems so far.

Using it 5 times a week, after 2 years, the bottom part started to not be as tight. It's worth their money and more.

It does not leak if you close it properly, it dissolves the powder very well, and the inner container is very useful.
