Good improvements over the RF-603, but some feature issues.

Reviewed in the United States on February 6, 2014

Verified Purchase

My RF-602 triggers are aging and that CR2 battery is a real PITA, so I thought I'd try picking up a set of the RF-603II triggers not only for the numerous improvements (locking ring, on/mode switch on the SIDE of the unit, the test button working in hand, etc.) but because these would be compatible without modification with my micro four-thirds camera (Panasonic G3). Worked great out of the box on both my Canon and Panasonic cameras.

But. Whether I got a bad unit or a bad cable, I don't know, but the set could not be used as a shutter release with my 50D and 5DMkII, so I am returning them.

In addition, I could not get another feature that was mentioned in the specs to work at all, which was the use of the PC port as a triggering input (from, say, a camera's PC port or a light meter) in Tx mode. I like to use a small optical slave in conjunction with the pop-up flash of my Powershot S90 to do radio off-camera flash triggering sometimes (I'm just weird that way), and it works fine with my RF-602s (which are old enough to still have the PC input port on the Tx unit). Couldn't get it to work. And the manual that came with the triggers describe the PC port as an output only (just like on the Mk I 603s). So if this was the feature you wanted the triggers for, you may want to wait and see if anybody reports success on this.

Other than that, the triggers were great are popping off remote flashes in my testing, and I'm sorry the other features didn't work as I expected them to.

Yongnuo RF-603 II with the YN560 III Flash

Reviewed in the United States on March 6, 2014

Verified Purchase

What great product and great price. the flash and the trigger hook up by radio, with no need for more than one trigger, no matter how many YN560 III flashes you may have. I have 10, they are such a great price. And the remote receiver is built into the flash, and works every time the RF-603 II fires. What a great combo. You can get 2 triggers and about 7 flashes, for about the price of the comparable Canon flash. Yes it has no TTL, but I never use it. If you love speed light photography, and don't want to spend the money buy the Yongnuo RF-603 II with the YN560 III Flash. You'll buy more.

Great little triggers!!!

Reviewed in the United States on March 23, 2014

Verified Purchase

I chose these triggers based on the fact that I only needed to remote fire some flashes I use for background lighting. As I sometimes need the flashes to be out of sight, I needed something that did not require line of sight and the 603's take care of the job without a missed fire as of yet. For the cost, nothing beats the 603's. Make sure you get the version II's as they have some handy upgrades over the originals.

Stopedd working after 4 firings

Reviewed in the United States on January 27, 2014

Verified Purchase

Just got mine today. Unfortunately one of them completely stopped communicating wirelessly after 4 firings. Changing batteries and trying different channels didn't solve the problem. All in all I would avoid the Chinese radio triggers like the plague. This is my second go-around (Meyin 604 also died after a week of use) and they all have had quality control problems. Cheap, yes. Money well spent, no.

Better remotes

These remotes are FAR better than the 603 C3 versions that came before them. Many of the problems fixed (has locking ring and failure rate way down). Very pleased with these remotes.

The trigger works fine, but the locking mechanism does not

Reviewed in the United States on July 26, 2014

Verified Purchase

The trigger works fine, but the locking mechanism does not. I locked in the transceiver to the hot shoe by turning the locking wheel mechanism and then after shooting I attempted to unlock it from the hot shoe by turning the locking wheel mechanism. While the locking wheel turns freely, the actual locking pin that locks into the hot shoe will not disengage. This is a poor design or construction that made this happen. It looks like I might have to break the transceiver off because there seems like no other option to remove it. This is problematic since now the transceiver will become trash and a loss of money to me due to it being a faulty product ... In addition, I have to be careful in the removal so I wont damage the camera. First, I will attempt to contact the "EACHSHOT" from which I made the purchase from to see what can be done on their end before I attempt such a last option action.

Yongnuo RF-603 II Review

Reviewed in the United States on January 22, 2014

Verified Purchase

If you are looking for a budget flash trigger, look no further. For the price, these just can't be beat.

Some of the things I really like about these:
Small, takes AAA batteries
Work at great distances, a 100m actually seems accurate
Triggers each time (tested for two days, about 1000 shots and fired every time)
Each trigger can be used as a transmitter or transceiver (transmit and receive), great for when you want to use a light meter
On and Off switch on the side (actually switch between OFF, TX, TRX)
1/320 sync speed, I could only test with my Canon 7D at 1/250th
Comes with cable for triggering camera remotely, make sure to get correct model for you camera (C1, C3, N1, etc...)
Has a Nut so it can be tightened to camera and/or flash
Works with Yongnuo 560III

So far I have not found anything I don't like about these.
Make sure to get Yongnuo RF603 II, the originals RF603 do not have the same options.

***Update***
Ok, so I've had these for several months now, they are still working great, I've even ordered a few more, have about 8 now. The distance that these triggers work is amazing, inside and outdoors. Also, I've had lots of shoots since switching to these and it's pretty awesome when you don't have one misfire after several days shooting and a couple hundred shots. Another example, at a wedding, I had 2 560exiii speedlights setup on opposite sides of the room at some where between 1/128 or 1/64 power and me and another shooter are both using them at the same time and still don't have a missfire. Wow.

These are awesome. 1 star off, since they wont test fire unless attached to a camera body.
