It's a shaker. It shakes things up well and is relatively easy to clean. My only issue with it is that mine arrived scratched and dirty, like it was found at the back of a shelf after a hurricane had ripped through the warehouse. I mean, I'm sure I'll scratch it myself, it's only natural. Just not great that it turned up in that condition.

Perfect on the go shaker, slim enough to fit in my bottle pocket and the extra compartment on the bottom means you can conveniently take powder for an extra shake with you wherever you go.

Very handy doesn't leak, good size in my bag. Easy to make milkshake without making noise, easy to wash. Truly recommend!

Definately appreciate the extra compartment for post workout whey protein. Washing is a small pain though but maybe because my palms are big

Handy little shaker, use it for BCAA's

If you want a nice and simple to use and clean shaker this is the one for you, only downside is that the shaker itself is very easily left with smudge marks which do not look good but do not play a role in anything other than looks. They get washed away with ease though but other than that this shaker is definitely worth it

Should order myself a few more of these good size, good quality and don't leak A++++

Best shaker! Light build and easy to prepare; the extra containment unit makes it super easy for on the go shakes.
