I didn't open it because I bought it my mistake. However, it looks like a very strong product, it's very heavy.

Very solid product. Well made. Unfortunately, a version with 2 monitors was released for only 10$ more the following day I ordered this product (on day one). I can definitively recommend this product. There are only two things i dont like: 1) some of the bolts to secure the arms to the post are not thread correctly and are difficult to turn. 2) The post is divided in two and the junction is a pain when changing configuration.

has the flexibility and features along with being strong and stable...bought a second one

very good quality.

I love everything about this except for the microphone boom arm. All other pieces are heavy duty and will last a lifetime. The scissor arm for the microphone is extremely fragile in comparison. It works but I don't expect it to hold up with repeated use. The mic clip that came with this is also of inferior quality, using plastic threads.
