The shaker completely mixes whatever supplements you use, there are not any clumps and or stuff stuck at the bottom.

First one I've ever taking that truly does what it says without all the tweaking like most!

For a simple plastic, it is much better than all of the metal shakers that I’ve spent so much money on. The built in shaker provides superior mixing and super easy to clean.

Product taste good, works as promised

All of these products are awesome
