After long hesitation, I took this cup to try. It is sent with detailed instructions and a small fabric pouch to store it when not in use. The size is great for those with normal flow; I never had any leaks, even the first day is more abundant, and even at night. The rod was a little too long, but I cut a bit with scissors, and problem solved. Knowing we can keep it for several years, it's over buffers for me!
