One of the best accessory purchases I've made for my camera besides lenses. The flashes and controller work flawlessly out of the box. Being able to control both flashes remotely from the camera is a huge timesaver when doing a shoot, compared to walking to each individual flash and adjusting the settings. I'm definitely considering purchasing more YN-560 III flashes in the future to take full advantage of the controller. The controller has 6 groups, so this is very expandable so you can build as you grow.

I purchased the 2 - YN560 IIIs and the YN560TX combo. I had difficulty configuring using the manual and help from YouTube. However, I finally got it - but one of the flashes would do everything but fire when I pressed the shutter. It would work with "Test" and work "on camera" - just not as a slave. I returned this flash and they shipped a replacement immediately. The new one has arrived and is configured correctly - after some patience. The Group setting had to be repeated numerous times until it finally engaged - instruction in this area could be improved. Both are now working properly. Full marks for on-camera adjusting - very nice, full marks for delivery and service - takes three-four days shipping through postal service. Now I am able to push through some testing with umbrellas in a studio environment. As a new portrait Photographer (but not a new photographer) I am confident I can do what I need to do to move forward. I shoot a Canon 60D and look forward to building my knowledgebase. So far I am more advanced than some of the videos because of on-camera adjustments. When learning to configure be patient and keep working through it. The instructions could be much better. You can adjust the length of time the LCD is lit through the Advanced Setting LCD feature- nice to have. Can't believe the difference in cost for the similar functionality. The three units are about 1/2 the price of just the transmitter for my camera - never mind the flash units. Shooting manual is easier than I thought and not an issue at all because you can control the power of the flash units. Go forward with strength, courage, perseverance and patience - glad I did...

For the price purchased and the functionality available in this Chinese made product, the quality is exceptionally better than expected. Performance is on par and would highly recommend this to any amateur just getting into photography. Very happy with this solid performer !

Third one I've bought.

The YN-560 III is an excellent manual power flash when TTL is not needed (e.g., in studio photography). It's distinguishing feature is an integrated radio receiver with multiple trigger options from three current-generation products. A Yongnuo RF-603 II is an affordable radio transmitter/receiver. I intended to use one on my camera (and more on my non-Yonguo flashes), but I opted for the Yongnuo YN560-TX controller when PhotoGear.com recently had a sale. The YN-560-TX goes beyond triggering, adding radio control of power and zoom for up to 6 groups of YN560 flash, very useful when flashes are above eye level on light stands. A YN-560 IV flash can also serve as master, but I prefer having less weight on my camera and generally do not want light coming directly from my camera when shooting people. So the YN-560 III is the perfect off-camera flash for me. I have two YN-560 III flashes (with the Nikon-style foot) triggered by a YN-560-TX (again for Nikon) on an Olympus E-M5 camera. They work properly together, and the light from the Yongnuo flashes correctly triggers optical slaves on my Nikon flashes. The quality of construction (sturdiness of the plastic body, non-removable battery door hinge, and head pivot smoothness) on the Yongnuo flashes is similar if not better than on Nikon SB-800 flashes. I like that no rubber button needs to be squeezed on the head before it turns or tilts through detent positions. Moreover, the Yongnuo buttons are easier to push than Nikon buttons while still working consistently. The YN-560 III does have deficiencies. First, the vertical viewing angle on the display is narrow. That makes the display very hard to read when the flash is high on a light stand or perhaps close to the floor. Before I used the YN560-TX controller, I needed to move my head around a lot to find the right viewing position or ended up lowering the flash to see it sometimes. Second, the low battery indicator and associated beep, only activate when the batteries are a few shots from becoming unusable. A continuous battery level meter would be nice, but the low battery indicator and behavior on the SB-800 is actually worse (flash goes to sleep with no audible warning and requires button press to wake). Third, like many third-party flashes, a ring must be screwed tight to lock the flash to a hot shoe. The screwing causes a locking pin to extend and retract, which is the same as on a Nikon so it is secure. It just takes more time than flipping a lever. Finally, the LCD backlight activates for a short time only when its button is pressed; it does not turn on automatically when other buttons are pressed. These issues are not showstoppers and I find myself preferring the Yongnuo flashes over Nikon flashes now. I am positively surprised at the overall quality of YN-560 III. The Yongnuo product provides a high level of functionality and outstanding value.

Awesome flash. Instead of buying another Canon 680ex I bought four of these.
