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.

Great product, works as expected!

I love this flash. Well built, great control, radio triggering works very well. I use these with the 560TX transmitter and the 603mk2's and it all works seemlessly together. Remote power output control makes it so enjoyable for hairlights and background lights. If I have any problem, I have a hard time getting the diffuser/fill card out. I have to get a pocket knife or some kind of thin edge to pull it out. Hoping it will loosen up over time.
