I brought this a while ago, and have hardly used it.
The shield aspect of the pop shield works no problem, as good as any I've used.
The problem with this particular pop shield however, is that to clamp it onto the mic stand and locate it in front of the microphone is almost impossible. I have tried every variation I can think of, and still cannot get the shield in front of my microphone, and so have now given up on using it. I use the wind shield that came with my microphone instead.
I would not recommend this product, unless you come up with an easy way of fixing the shield in front of your microphone
