Exactly what I needed.

This is exactly what I needed to power my other strobe lights and other off camera lights. I can even press the shutter button on the device itself when the sync cord is attached to the camera. But you don't need it if your camera doesn't have a sync input.

Just ok. Not compatible with one Godox but is with another. Booo

Ugh. I have 3 flashes and it only fires 2 of them. It messes up my ability to rotate based on need. Spend the money & get a better set. On top of that, Adorama had me talk to FOUR people who could not answer simple product questions. It's my emergency set, not something I feel good about relying on.

Good

Works perfectly & very happy to have saved money by buying from Adorama instead of another major online retailer. Setup is easy even for someone like me who has never used off camera flash before.

Works great as shutter release without flash for Canon 6DM2 (however I want my flash to work too)

I'm intention is to use this as a shutter release while using my flashpoint to fire the strobes/speedlites. Unfortunately flashpoint won't work while using the shutter release in hotshoe and stacked. I have a canon 6DM2. To confirm I have the 3 pin connector plugged in. The yongnuo is in my hotshoe with the flashpoint in the youngnuo hot shoe (Joanie Simon on the Biteshot - youtube has a video "what's in my hot shoe") her's works with a Canon 5DM4. So the issue may be my canon 6Dm2. I can still use it if doing continuous flash, however I use strobes 90% of the time. If anyone reads this and know's a workaround let me know.

Great trigger Great price

I am a Flash Point user but I needed a remote to fire my camera without fussing about with creating a delay with my flash settings. This remote fits the bill for the job, it has great range and makes the job easy.

Inexpensive Triggers Work like a charm

Item works as expected. Great inexpensive way to remotely fire speedlights. The transmitters themselves aren't as streamlined shaped as I would have though, they're much chunkier. Not too obtrusive but not the most ideal to pack away and forget.

Awesome for little money

I was a little bit hesitant, but they're better than the optical slave I used, especially in the brightly lit Caribbean island of Aruba. They worked just fine on the beach at family shoots, weddings, etc. I don't use them that often, but for me, a LOT of bang for my bucks!!!!

Sony a3000 and RF-603 ll: Bad match for compatibility? + bad manual

I was under the impression that a RF 603 for Canon would also work as a basic trigger for a Sony a3000 on a YN 685 (according to some reviews). Apparently not, as all that happened was very erratic behavior from the 685. Manual did not help. Three stars for this, because I am still not sure what was going on.(Not sure if 603 was defective.) BTW, my YN622 works great with the 685 on the Canon. So still looking for a trigger for the Sony and another speedlite. And YN manuals suck.

Great little triggers!

I wasn't really expecting anything good for such cheap triggers but these guys fire every time! I've used them in the studio for several years now with various flash brands and always have spare ones around, just in case. But haven't needed to replace one yet. Good stuff.

Works with YN560-TX

I purchased this to use with the current transmitter I already had to run a monolight. This works great. I was also able to use the included cable to attache from the YN560-TX to the camera (for a Canon camera) and use the second trigger as a remote to run the camera. These can also be used to trigger the TN560 IV from the camera.

Fine Tool

Was skeptical at first but was pleasingly surprised, it does what it suppose to do! Setup and sync was easy, only downfall, I can’t seem to get it to sync with one of my flash, Good for the cost.

Very reliable so far, works great with Canon and Sony cameras

I was referred by a fellow photographer to these triggers and so far for the money, they can't be beat in my opinion. I have used them to trigger Yongnuo flashes, Flashpoint flashes, Canon flashes and Alien bees and all work great! These triggers also work great to trigger from my Canon or Sony body which is awesome too.

Works like a charm

By Rudi C.

I would recommend this if you are running a yongnuo speedlite. I have the yongnuo yn560lll speedlite and it's designed to work with the RF602 or RF603 wireless flash trigger. I'm running the Canon 7D mkll and I can run one of the transceiver on camera, connect to my flash wirelessly off camera, and have the other transceiver in my hand as a wireless trigger for my camera and trip the off camera flash at the same time. I dont know if these will work if you have a Canon or Nikon speedlites for ...

Exactly what I needed.

By ARTURO P.

This is exactly what I needed to power my other strobe lights and other off camera lights. I can even press the shutter button on the device itself when the sync cord is attached to the camera. But you don't need it if your camera doesn't have a sync input.

With a host of features and pro-level capabilities, this wireless trigger from Yongnuo lives up to the brand's reputation for quality gear and components to suit your photo flash needs. This particular set of flash triggers can operate wirelessly or with a PC sync cord for improved connectivity. This unit adopts a global FSK 2.4GHz wireless channel that can work anywhere and in suitable environments can reach up to 100 meters. It can be set to a single transmission state, which is more convenient for testing the flash and it can also be set to transceiver state. You can also automatically switch between the two. Transmitter supports single contact triggering, as well as wireless triggering, via the camera hot shoe. It's also PC-sync ready and can be connected to a network of flashes and shutter triggers for studio use. The highest flash sync speed this light is capable of is 1/320th of a second; different camera models may only be capable of 1/250th.
