It's exactly what i wanted when i pictured buying a shaker. Not perfect, but pretty dang good at it. This is the cheapest one i could find and it works perfectly.

It mixes everything well with no leaks. It mixes very well, no clumps at all. It even mixes well when adding a plop of wet food to the kmr for weaning kittens.

Shaker bottle is must buy for gym enthusiasts. Flip lid make it easy to drink without spill or dribbling. Pours easily into kitten bottles, and had never leaked.

The lid splits along the molded seam very easily. There’s a fine line between not tightening it enough where it leaks, to tightening it too much where the lid breaks.

My three blender bottles are in the trash. I wish i didn't get a product that was poorly manufactured. In manufacturing these batches are sold off in lots at a fraction of a cent on the dollar.

Regret this purchase as the other one works great! Dont buy this.
