I love the flexibility of this arm which is essential for my very particular home office setup and i'm now getting rid of my Rode PSA1+ as that one is a pain in the ass when it comes to adjusting where the mic is screwed in whenever I need to switch up the orientation of the mic. with the Rode PSA1+ you have loosen it and then adjust position and hold it while tightening it up again, whereas with the Avermedia arm, you can simply rotate it. Additionally, the built-in rotating screw mechanism is such a simple but genius design which makes it way easier to screw on a mic there.
However there are some important things to consider. Go read the review by Tommy Thao to get all the details but to recap:
1) The cable management system is not designed for cables thicker than 6mm which sucks if you have thicker XLR cables.
2) The arm is weak. Im using a Shure MV7 which is a lightweight mic but I still found that I had to tighten the joint screws a little bit. Heavier mics will definitely not hold in place without tightening joint screws to the max and even then, it might not be enough depending on the weight of the mic/accessories.
3) Joint movement is tricky. I absolutely love the flexibility of this arm, however it is a bit tricky to get used to. You'll have to play with it a bit to see how it works but this wasn't a huge issue for me, I was able to figure it out for my setup fairly quickly. YMMV tho.
4) PRICE. This is where I think is the biggest problem with this arm. Its waaaaay to overpriced in its current state; this arm should be around $130. If it didnt have the issues that myself and others have pointed out then definitely would be worth the asking price. It needs to be beefed up so it can handle heavier mics, take thicker XLR cables and if they could add a built-in extension tube so the mic can be placed further from the arm, kind of like a mic stand boom arm that can extend out, I would gladly pay the asking price.
The reason I personally would like boom arm extension is that the way my desks are set up, the arm gets in the way of my monitor on my right hand side so I've added my own extension tube so I can place the arm out of my line of sight but still have the mic right in front of me with out blocking my view. Adding my own extension tube was a quick fix but its obviously not as secure as a built-in one would be. Also, since this adds weight due to being off center and whatnot, they would definitely need to beef up the joint tension system.
So overall, I love this arm because it works for my very particular setup and light weight mic, but I do believe it should be less expensive. Here's hoping theres a version 2 of this arm that address all of its short comings.
