I have this mic screen set up in the main vocal booth of my recording studio. It works great in further eliminating unwanted room noise and ambiance, and allowing for a dead and flat vocal recording.
So the product works, it does it's job, but I was not fully pleased with the build quality of the product.
The product is fairly simple to put together, but comes with no instructions. There are a few images on the box showing different ways to put it together, but it can be confusing getting the mic screen set up correctly for how you want to use it. It's a modular system and there a re a few parts you can take away or add, so it can be confusing to built at first.
When built and mounted on a stand, the mic screen can be a bit wonky and move about, even when tightening all possible screws. Not a major problem, more a slight annoyance.
One thing to consider is the price of this unit. It is much cheaper than any other mic screens on the market, and it does do it's job very well. I would definitely buy again if I needed another.
