I'm running low on C-41 bleach. Can someone comment on this bleach for manual development in a small tank?

It's Kodak Flexicolor RA (C-41RA) Bleach Replenisher NR for Color Negative Film. According to the product description, it "requires no mixing; it is packaged ready to use." I realize this is packaged and marketed for labs, so I'm wondering if it works out of the box. It's not a Part A. Thanks.
