I have been beta testing a new Campy product direct from Italy recently. Lucky me!
The early results are as follows: Smooth, quality packaging, and all the goodness that you have come to expect. I highly recommend. Cavet Emptor: DO NOT mix with Japanese sourced items. Marinara and Soy Sauce are incompatible, and will lead to terminal failure of your project.
My performance marginally increased after the use of this product. Will I use this product again? Yes.
The price was more expensive than lesser known brand, but worth it in my subjective opinion.
