Awesome for a shaker
This thing is awesome.  Very well constructed, extra thick side walls, the top screws on tight, and the handle is perfect.  I was skeptical of this new vortex shaker thing, having used shaker balls for years, but that in conjunction with the rounded interior base leaves no powder unmixed.  I love it and plan to buy me a second one to have in case anything does ever happen to this one.  I plan to throw all my old shakers out and replace with this one type.
