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.

5.0 out of 5 stars Seems to work great and more economical January 4, 2012

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.

5.0 out of 5 stars Very reliable - great value November 3, 2011
Amazon Verified Purchase
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.

5.0 out of 5 stars Very reliable! November 21, 2011

I purchased these to replace a more expensive set of triggers that were giving me problems. I am very pleased with the performance of these! They were ready to go and no misfiring. I also like that I didn't have to put one of my flashes on the camera hotshoe, I fired both of them remotely. I highly recommend these!

5.0 out of 5 stars WORKS GREAT! September 15, 2012
Amazon Verified Purchase
I've been using this on my Canon 5DMKII for a couple months now. I've had zero problems with this unit.

Recycle time: It works every time I press the shutter. Meaning no misfires. So far.
NOTE: Of course the recycle speed of your flash is going to be a factor in that. If your flash recycles fast then you can shoot fast. It keeps up if your flash can. If you try it on continuous and it skips a beat, it is most likely telling your flash to fire, the flash just isn't keeping up is all.

Ease of use: It doesn't get any simpler.
1)Insert batteries into receiver(s)
2)Attach transmitter to camera
3)Attach receiver(s) to flash(es)
4)Turn on receiver(s)
5)Make sure all units are on the same channel (1&1 1&2 2&1 or 2&2)
6)Play

Distance: I can't say how far they'll go through walls. Walls vary. But out in the open I get approximately a good 135ft (41meters). They say it's only 30 meters, which is about 98ft. So expect a little more than what they say :)

Build: Well, it's cheap plastic. It's been through some bumps and what-not. I can be pretty abusive to my equipment. Yet I try to be nice to it considering it's just cheap plastic. But sometimes things happen. So far so good.

Batteries: Receivers: AAA's. Does NOT come with. Just in case you were assuming it would. 2 per receiver (4 total). Transmitter has a built in battery. Which I found to be a little odd. It is easily accessed via the SMALL phillips screw on the bottom. 23A 12V. Radio Shack will have it if needed.

Notes for proper use:

1) MAKE SURE the batteries are installed in the receivers properly. Simple things can make you frustrated when your brand new product doesn't work.

3.0 out of 5 stars I Like It But Had I Paid More I'd be Angry July 14, 2012
By John
Amazon Verified Purchase
So I have had these for a few weeks. I use them with two YN-560s and a canon XSi. Out of the box they didn't fire my flashes. So I did some research and found that you have to remove the transmitter's battery (and replace it) to make it work. Strangest thing ever, the receiver would indicate that the shutter had gone off (Red LED on receiver) but the flash would not fire. After power cycling the transmitter it worked great.

I thought that could have been a one time thing but its not. I have to do this every time I don't use the transmitter for more than a day. So i hacked it and put a little switch inline. Now I just turn it on and works. The flash fires 95% of the time.

The build quality it what you expect at this price range. What scares me the most is the plastic male shoe on the receivers. I have these connecting my flashes to my flash mounts 7 feet in the air. A scary place for these plastic shoes to fail...

For the price I got these at I can't complain but I also can't love them.
