Review on ProStainless Protein Shaker Blender by Aaron Urena

Not the same as those that come with branded shaker bottles with mixer/whisker balls. They have fewer turns and are squeezed together very tightly, making them look flat when you first open them. The metal feels as thick as those in the original bottles, but because they have fewer threads, they feel brittle. I throw them in the laundry, then I try. Not too impressed so far. I bought these based on a 3 pack review that said they were identical to the original. Hoping they don't look like the cheap ones everyone says don't blend well or blend forever. I will update this after use.
