This is a very heavy duty flex arm.

Makes things possible that would have been hard to do otherwise - money well spent!
I use it with Manfrotto 2909 Super Clamp.

Seeing the image of this item doesn't quite do it justice - I was expecting it to be a relatively compact, flexible arm (despite the "Heavy Duty" tag on it). I was pretty impressed when it came and was as heavy, thick and tough as it was. The arm itself is almost an inch thick throughout, almost 2 feet long, more than a pound and a half and very tough.

I bought this based on the information that it can hold 1.1 LBs - figuring this would hold a speedlight and not be TOO difficult to twist around.

It can definitely hold a speedlight - I'd imagine it can even hold a DSLR (But I'm not about to try it!) - the thing is, and I'm not sure if it's a good thing or not, the thing is REALLY tough and a bit hard to bend (it needs some force - you'll need 2 hands to bend it). This is both a good thing (it won't bend on it's own!) but a negative if you need to do anything more than slight bends, or need to quickly adjust the angle.

One end has a standard stud-end for a Superclamp (with a 3/8" threaded hole, so you can attach it on top of a lightstand tip). The other end has a threaded 1/4" tip (to attach something like a wireless trigger for a flash).

The great thing about this is that while it's heavy, it gives some great flexibility (no pun intended). While you can always superclamp a flash to a railing, you're somewhat limited on it's angle/direction. This lets you superclamp a flash to a railing and position it EXACTLY how you need it.. angled, straight up, straight down, bend around, etc.. Sometimes the length is a bit too much (at close to 2 feet, you sometimes wish it were just a few inches). It's not the lightest thing to carry (superclamp + arm = 2 lbs), but compared to a lightstand and ballhead, it's much nicer.

I've been a bit mixed on it..

I agree with another user's comments: this is a great item, but the bolt at one end was almost immediately loose on the unit. I had only been using this for 5 minutes, attaching it to the Manfrotto super clamp and bending the item at a near-90 degree angle. I then attached a small item (a 90-led light) and then noticed the flex arm was rotating a bit. At first I thought it was because I hadn't tightened the super clamp properly, but I checked and that wasn't the case. The bolt on one end of the flex arm was actually loose and rotating within the unit. I was worried I would have to return the item, but I decided to simply tighten the bolt with a wrench. I hand tightened it and it seems fine now. This is worrisome though, since it makes you wonder about the quality. Plus, I was holding my breath as I hand tightened the item, half expecting it to snap or suddenly just strip and freely rotate. This isn't something you want to do 5 minutes after you start using a product.

Since this happened to at least one other person, Manfrotto should check this issue before distributing these.

I still gave the product four stars because it is quite a useful tool. I am attaching it with a superclamp to a Manfrotto monopod and attaching a shotgun mic to it, as well as a Zoom H2. This setup makes me look like a professional news reporter. Pretty cool. :-) It will be great for recording bands, as the whole unit doesn't take up anymore room than my profile.

UPDATE 3/13/12: After using this item for a while longer in the field, I found that the hand tightening of the troublesome bolt has held.

This extension arm is strong enough to support relatively large reflectors, light fixtures (I use it with a compact fluorescent socket + reflector bowl), or flash heads at crazy angles and without moving a bit. It is heavy and requires some strength to position (I can't move without holding the light stand it is attached to with the other hand). Think of heavy bicycle locking chain and you'll get an idea of the weight/bulk.

It can be attached to the receptacle of a super clamp or screwed to a 1/4 (I think is 1/4... could be 3/4 don't remember at the moment) adapter. I have mine screwed to the end of a light stand to provide a flexible support for a light fixture. The build quality seems pretty solid and I would not doubt recommending it.

I must mention that I also tested the non-HD version, which is lighter (but not a lot), but it was unable to hold my lamp in the position I set with arm bent ~90 degrees in the form of an "r". The non HD version might be good for flags or light flash units, but struggles to keep heavier stuff in place.

This thing is awesome. I bought it along with a SuperClamp to affix a GoPro to an ocean-going outrigger canoe so that I wouldn't have to use GoPro's adhesive mounts. I needed something that would be strong enough to hold the camera in place as the boat pounded through the surf or if the boat flipped. It certainly passed the test and never let me down on the water.

I've since used it for all sorts of odd jobs outside its intended studio use, including sometimes as a makeshift tripod for my 50D DSLR. I've had it over a year, in and out of the ocean, and it is still as strong and rugged as when it was new. For those of you wondering how well it will hold up in the studio, I have no doubt that it will outlive you.

It should be noted that it is big and heavy, and it is not easy to bend the flex arm. I assume this is what gives it its strength to hold up whatever it is that needs to be help up, be it lighting, a DSLR or whatever odd job you find for it.
