I have been using my cup daily. When I initially got it I was skeptical, but even with 2 servings of powder To liquid I still get no clumps or unmixed powder. Excellent product!!
Amazing service I had a problem with the certain colorway and sent them a text. Moni instantly helped me and sorted things out for me. She’s the best and such a good worker amazing customer service!
Love this shaker better than the blender bottle. No ball spring needed!
