It took me a while to actually install this boom arm, mostly because I had to decide where the most advantage would be. I ended up mounting it on the ceiling; when I ordered this, ceiling mounting was listed as an option, but it isn't now. This makes sense as the light mobility isn't the same with that kind of mount, but that is where I needed it. I have been a bit nervous about trusting it with an expensive strobe, but it is holding well. I plan to add a safety strap, just in case something gives and my strobe drops, but as of now, it is working well.

Mounting requires a strong wall - I wouldn't trust this on drywall less than 3/4" thick. For stud mounting, you need at least a 2x6 board. I used two 2x4s attached to two joists in the ceiling, then mounted the light directly over one of those joists for added support. I also used my own mounting screws - the ones that come with this bracket will never hold the weight of an AD600Pro strobe and large softbox. The pressure of the softbox on the arm increases the weight strain substantially, so even though my total kit weighs less than 20-lbs, I had some serious concerns over how well it would perform.

The boom arm is secure once you tighten the nuts. I am able to extend this to its full length, though I won't use the softbox if I do - it just seems like it puts a bit too much strain on the arm. You can remove the mounting head and position it back on in a number of configurations. The arm swings well, and if I mount a positioning chain on either side, I can even use it on the ceiling, but that function is best for wall use.

All said, it is a good boom arm for the money. I am considering two more for wall use to get my tripods out of my floor space.
