I bought this new and tried it once, but I already had something similar that was sufficient, so I've kept this stored away. However, it's very convenient for those who don't have a soundproof environment. With just this one, you can significantly improve room acoustics. Those seeking a higher-quality environment might find it lacking, but it's useful for those who want to reduce room echo during streaming or recording. *Due to the product's specifications, it may be difficult to use with very small microphones.* For the microphones I own, it fit easily on the AT4040 and Blue Baby Bottle. It's a tight fit on the C214.
