Stays closed when shaking. Great product
Love it for BCAA's , creatine, mio, water etc. It also works well with Protein, and doesn't clump as much as you would think. It doesn't use a shaker ball, but instead uses a plastic waffle pattern to pass the liquid and powder against and mixes well. The insert can be taken out and toss in a spare blender ball and it won't leave. Hope it helps!
Love this shaker cup. Never have problems with clumbs and my protein shake's taste great. Placing another orderived for 2 more
This shaker is amazing and super easy to clean. The inside screen helps prevent protein from clumping up! I have 3 of them and they are all very durable!
Its a good shaker cup. I use it everyday.
