Based on some reviews I had really low expectations but thought the low price was worth the risk. Pleasantly surprised by this little thing. I have an AT-2020 USB (old school, not new plus) and both the shock and pop filters fit like a glove. Hold still - especially for a moving mic - this pop filter is a breath of fresh air. I use my mic for acoustic guitar demos, as well as podcasts, live streams, tunes, and anything else I can think of. . I've kept it sideways on a stand since delivery and the mount is holding up well. If it frays, extra ribbons are added, otherwise I can just use a hair tie. Don't waste your money on something more expensive.
