I got this mounting popkiller as an additional item of a bundle and great thing I did - its really great. It obviously does what it is intended to do - gets rid of the unwanted air pushes that create a "pop" sound (therefore, the name), but quality is also an additional plus to it.
The connecting arm (tube that connects the mount to the popkiller) feels great and is flexible and firm - no matter how you twist it, it will stay firm and steady in any position. I think the quality shines even brighter in regards to the popkiller nylon-cover. I have tossed in my bag when traveling around with the microphone and in has been ripped or damaged in any way - it may seem fragile, but I have to say, It is surprisingly durable. The price, which isn't a lot for these popkillers, definitely gives more what you think you might get.
If you have a microphone at home or at studio that you want to equip with a great, low-price popkiller, I highly recommend getting this one. It does its job perfectly, is easy to use and mount, can be twisted and turned for your needs and has great durability.
