I saw this pop filter on a YouTube video by Postcastage when he held it up in his fingers and used it - and then I tried to buy one and found out thia Rycote pop filter is only a replacement for a very specific Rycote frame that is not universal - I bought the filters anyway and use it clipped into a gooseneck with a large mobile phone clip and it works perfectly without the frame - the extruded plastic design is thick and stable enough to work without the frame and I have tried it against the Rode Rycote metal filter and other nylon filters and this is the best - I got five in this pack too. It’s one of those products that just really works for me, and apparently its washable too.
