First of all. This bar is a lot bigger than it looks in the photos, it also not the lightest bar out there. So keep that in mind of you need to use it in tight places, like under a partially closed piano lid, or on the end of a long mic-stand boom arm. This isn't a huge problem in the studio, but it can prove difficult to use it live when you only have standard light weight tripod-stands and need to extend the boom arm.
With that being said, this is a excellent product! It's got markings for easy and exact setup, and every mount can twist and turn every which way making it a joy to get the microphone placement just as you want it.
Just keep the weight and size in mind.
