I received two jars of fougere mania in the new siero base, and shaved for the first time with it. The weapon of choice was a Feather Artist Club SS paired with a Kai Captain Mild blade. I've included a picture, along with some of its closest competitors, and the initial assessment is very good. It offers excellent slickness, but I'm not sure the post shave feel can match the GD Nai base, although is is still excellent. More shaves are needed to get a better idea of the performance.
