Question: Is this bracket plastic or metal?
Document: This bracket is surely cheap, but really does the job. I switch between using the flash and bulbs with umbrella attached. Granted, it's some sort of cheap solid plastic like material making it look like it's metal but common sense is don't need to tighten down so hard taking chances to strip the threads. I've gotten 4 of these and will buy from Cowboy Studio any day again.
This is a very good bracket with metal Flash holder with an adjustable facility (first time I saw this adjustable facility) . Rest is hard plastic-fibre and all in matt black except one screw. Elegantly designed. Umbrella stem can be locked at desired position. (this feature is not available in many  this kind of brackets!) Prompt delivery by the supplier. I will recommend this with no problem to anybody.
One I added even just a small umbrella, the entire solution became unusable. I simply could not tighten down the clamp onto the stud in a sufficient manner.Despite my experience, this is a good umbrella holder bracket for basic traditional needs. The build quality is OK, but not comparable to Manfrotto for example. The highlight of the build quality is the all metal cold-shoe clamp system whereas the lowpoint is the threads on the screws, which can quickly become bare if overtightened.
If you need one urgent or as backup, its ok. But its all made of plastic.I ordered the same item from a different vendor and the other has the top parts (flash bracket) is made of aluminum, the body feel and looks with more quality.I'll use with caution, doesn't look solid.
The umbrella and the flash head need to be in an angle so the flash hits the center of the umbrella and illuminates the surface evenly. With this bracket its almost parallel so only/mostly the top half is illuminated. I got the kit with the three umbrellas and the stand. I've been lucky since I haven't stripped any of the plastic screws. The umbrellas are well built, although small, the stand is good for holding my sb-700 and extends more than 6 foot..
&#34;Made from an aluminum alloy&#34; is a lie... the unit is almost entirely plastic, with only a few metal pieces.
I sought this out to convert my on camera LED lights to stands. Works beautifully! It is heavy plastic with a metal hot-shoe lock.
Plastic threads and a metal screw just don't mix. I guess you get what you pay for. :(  I wish I had kept all of my packaging to return this item.
I've used this a few times and it seems very solid, though it's made of plastic. I'd like the areas that get the most use to be metal, so I assume I'll be replacing this after a while. But for the cost it lives up to expectations.
Came in time, metal construction with some parts plastic. Metal for the shoe and plastic for when tightening to stand so be careful to not over do it. Does its job and holds flash in place. A lot cheaper than big brand ones.
Answer: Mostly metal, very heavy duty.  I used it all the time with canon 580 ex.
