5.0 out of 5 stars Are you kidding me? December 4, 2011

First let me say that the delivery was 2 days earlier then I expected. Next, you're a sucker if you buy any other triggers and are not a pro.

It arrived in a nice looking box and was well protected.
First thing I did was bought batteries to test them out. You do not need a flash to test them out, but I recommend you do to no be miss led. For example; I pressed the test button on the trigger and a little red light on the receiver indicates that it received a signal. Now I did this right when I put my fresh batteries in. It did show some miss firing on one, but, when I tested it with my flash (SB900)it never missed fired not one time. It appears to me that the light doesn't pop each time you press the trigger button. However when the flash is on the receiver, it has worked every time.
I Tested it with 2 walls(about 30 feet straight line)between the flash and camera and not one time has it miss fired. I took about 70+ shots so far. Not bad for day one. I do expect them to miss fire but so far the stats are great.
As for the build, It has metal hot shoe mount and metal screw mount. The tightener is plastic and the shoe is plastic. You don't need to tighten the trigger at all. It fits snug.

Update. I got my other flash last week and both receivers still hasn't miss fired.

I freaked out at first when I saw the PC sync cable that comes with this set. I don't have a PC sync cable port for any of my gear. But I tried it out anyway and it works great anyway. You do not need to use the PC sync cable at all if you don't want to.

Basically you stick the transmitter into the camera hotshoe and place the receiver onto the flash. Then power up the flash and use it in Manual mode to set the strength (e.g., 1/4 strength). Make sure the batteries are in the receiver and that the transmitter and receiver are on the same channel.

Take a test shot. If it's too bright or dark, adjust exposure compensation/flash compensation and/or flash strength until it's just right. Then you can fire away without having to re-adjust!

I bought this set in case one of the receivers breaks; that way I don't have to order another receiver at extra cost.

Way cheaper than many alternatives like Pocket Wizard.... yeah you don't get TTL with this, but frankly even with TTL you may have to make manual adjustments anyway.

I took a lighting class and these units were recommended to the students. I picked them up along with a couple of YN560 speedlights. Coupled with my D7000 they work very well both indoors and out. I haven't yet found any problems with interference. I have not used them at any extreme range so cannot say how well they would work at large distances but then with a speedlight you would be unlikely to be in that situation anyway. I recommend these units to anyone considering using off-camera strobe/flash.
