Recently, I was using a wired lavalier microphone that I had purchased two decades ago but had not used for some time. I found that the foam windscreen had deteriorated and would soon turn to dust. That is not an unexpected condition; it's a characteristic of this type of foam and has happened on several other products, such as my excellent but old Sony headphones.

Hundreds of replacement foam windscreens are available on Amazon, but I could not find one that would fit perfectly on my Audio-Technica mic. So I got in touch with Audio-Technica and was promptly sent a replacement, at no charge. 20 years later. For an out-of-production mic.

That kind of support isn't around much these days. Kudos!
