I've passed through number of those windscreens for the last 10 years, and I don't see any reason why spend more than that, when these cheap ones work the same as the more expensive ones. Never ever had any wind or 'pop' sound when these where on.
I probably wash them more often that I should, but I think having decent hygiene should be a common sense, and even after so many washing cycles, they still last at least entire year or more.
Sonically, they are absolutely transparent and does not affect the sound of your microphone at all.
The foam is pleasantly firm and doesn't feel cheap at all.
They'll fit on almost any microphone brand.
Unbeatable value for money while still being very effective and durable.
