These are manual triggers and I debated on purchasing a trigger set that was ETTL enabled for my Canon system but in the end I decided that I end up shooting almost exclusively off camera lighting in manual mode and these would do the trick. I have had zero issues with these triggering each other (when connected between my DSLR and my Canon 580 EXII). They work flawlessly.Also, I then decided that I needed another speedlight and went with the new YONGNUO 560 III for less than $100. This is a manual flash ONLY, but the cool part is that it doesn't need a RF 603II attached to it because it has a receiver for this trigger BUILT IN to the flash head. Now I have one trigger on top of my CANON DSLR, and the other attached to my Canon 580 EX II. The Yongnuo 560 III doesn't need a trigger and I can use a two speedlight setup like this. If I need a third light later on, I will most likely get another 560III to work with these triggers. The YN 560-TX controller works with these 560III flash heads and is good manually control your lighting groups, but seriously, right now my lighting is all within several feet of my reach and I'm not that lazy. The controller in this case would be a good idea if your speedlight is INSIDE of a softbox and you have to open the box to adjust the power, but otherwise with umbrellas and other types of light modifiers that you can access your speedlight easily, these RF 603II triggers are a simple, reliable, and effective way to trigger off camera flash.They arrived exactly as described, in new packaging, in a timely manner. I am very happy with my purchase. ### ⭐⭐⭐⭐⭐ I wasn't sure how good these radio remotes would be *by F***M on November 26, 2014* I wasn't sure how good these radio remotes would be, but they work perfectly with my setup using Sony mirrorless cameras (A7, a6000, RX10) using the Yongnuo YN-560 flashes with those set to manual, configuring power and zoom to my liking, usually shot through Wescott umbrellas. Having taken around 100 shots, since receiving these, there were no misfires using the "TRX" setting on the side switch. This is the setting for hotshoe mounting of the flash on the remote. When test firing the "TX" setting is used on the triggering unit and "TRX" on the flash mounted unit.I have enough confidence in these to have just placed an order for another set. The fact that these are multi-functional "transceivers" that can play either a receive or send function you get a lot of value for the dollar, especially when you consider that a pair of Pocket Wizard X units run $180. For me in buying two sets that's a $300 savings. Although I haven't had the opportunity to test the range, it is listed at 100m and I can't see my use ever getting to that range as I'm usually in a studio or at short range outdoors, using to either complement or overpower natural lighting.Again, for the enthusiast, or even the professional, you really won't believe the quality and performance of these thirty-dollar radio remotes. I even dropped one on a concrete basement floor with no visible damage and no impairment of function. ### ⭐⭐⭐ BE CAREFUL!! *by R***E on April 28, 2015* BE CAREFUL!!! These are great products when they work, however, while attached to my camera the safety pin became stuck in the down position. I was unable to remove the device from my camera & had to disassemble it to get it off. My camera's hotshoe was damaged in the process. Upon doing some research I learned this issue is not uncommon & many people have faced the same solution. I had to return them & am too afraid to give them another shot. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/1674135-rf-603-ii-16-ch-wireless-flash-trigger-for-canon](https://www.desertcart.pl/products/1674135-rf-603-ii-16-ch-wireless-flash-trigger-for-canon) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-26*
