The strainer on top helps to fully mix whatever powder you're adding and the metal construction of the shaker makes it super easy to clean.
Looks amazing, love the full idea of the shaker with the outside steel look and the interior shaker ball paired with the grate or whatever up top.
Problem i have with it, which tends to be the most important part of the shaker, is it leaks due to not a great seal on the lid, and it's a bitch to get off once you put it on. Like someone said earlier, the 9 dollar generic shakers dont leak so this one shouldn't.
Fix the leaking lid issue and I would give this a 6 out of 5.
As Described, and then some
Pros; Two Stage blender mixes everything with hate and discontent
Cons; You have to clean it
I like the strainer in the lid that breaks up the larger clumps of protein powder, that's a great feature, but that's about it. It's hard to clean, sweats when cold milk is put into it (so it's too messy to have sitting on a desk) and the threads to hold the lid on aren't that great. A good start, but not the best shaker bottle I own.
