Hello There, the MZW 400 windshield I have the Sennheiser MKE 400 Directional microphone mounted. It is very fast, with a single click. To get the full power, ie large frequency range of the microphone, it is better in advance to remove the foam protection on the mic. Even in high winds no more bubbles in the deep tones. I have neither the tone with a headphone controls, which suppresses external noise. So once again the windshield is very effective and that's why I recommend it.
