When I opened the package, the little lock thing on the side was very loose and broken. The bottle itself has a very loose attachment with the lower compartment, causing leakage to my entire bag.

This is without a doubt the best shaker anyone could ask for, You can even mix the mega gainer shakes in this! Never leaks and the grate in the lid makes shakes silky smooth. 5* lethal job

There’s just nothing to improve about this shaker, it is the pinnacle. The extra storage is brilliant, the hexagon grate that fits onto the lid section is brilliant, everything’s brilliant. I haven’t had a single shake that hasn’t blended enough with this shaker. Highly recommend 5* unreal 

The 2 screw on compartments are so useful to hold pre workout and protein during the day! Saves you having to take tubs. 

Does the job, but the scale on the side is almost impossible to read when trying to measure out a liquid. Also the stopper is bit stiff to close completely.

Great shaker, Stores my protein for after the gym and Meal Replacment shake while at work storage for the whole working day.  Mixes product well for a smooth shake 

Happy with my order it came quicker than expected and tastes really nice thanks 

Probably one of my most useful purchases from this glorious site. I often drink 1, less frequently 2, protein shakes a day to top out my protein goals for the day, and this shaker is perfect for when I need to pack one to work or wherever else I may be going. I can store the milk in the shaker itself and the powder in one of the screw on containers and mix on the spot. On days I go to the gym after work, I can easily grab it out the fridge and mix it as a pre-workout energy boost as I'm normally running on empty by then as my lunch is usually quite light. The blending grid (whatever ya call it) is slightly conical with hexagonal holes and seems to mix really well, I have two shakers, this one and one with the more standard flat square grid and it mixes noticeably better than the square one. The cap snaps closed and holds on very tight, just about not too tight, which is perfect because I can shake without having to hold it shut. It is a solid bit of short plastic, not the dodgy bendy kind meaning any of the liquid that gets onto the cap isn't flung across the room when opened! I couldn't recommend this shaker enough.

Worth every penny, don’t buy a cheaper option.

Awesome shaker, each container can store just about 50 grams of powder and well worth the money.
