Best for users who prefer a sleek, minimalist look in addition to portability.
References to its safe-and-effective operation include the same CE & GMP facilities and safety claims as the white version. A limitation to consider is that the diffusion capacity is tied to USB power, so performance can depend on USB port availability or hub bandwidth.
