Neewer 16 channels RT-16 Wireless Studio Flash Trigger, Compatible with Neewer S101-300W, S101-400W, S101-300W PRO, S101-400W PRO and Other Studio Lights

After my old wireless sync went kaput, I needed a replacement. This one worked great.Older studio flash systems, like my Novatron use a two-prong sync plug that closely resembles a standard 120 VAC electrical outlet. For at least one apparent reason, newer studio flash systems use either a 1/4" or 1/8" two-conductor audio plug, so they cannot be accidentally plugged into an AC power outlet.This Chinese-made NEEWER RT-16 Wireless Studio Flash Trigger comes with the 1/8" plug and a 1/4" adapter. Since I had long ago made a patch cable to adapt 1/4" plug to my flash's two-prong socket, I was able to plug this trigger into my adapter cable and have it work with my setup out of the box.The transmitter comes with a 23A 12-volt battery that can be enabled by pulling out the insulating tab. The receiver requires two AAA cells that are not included. The receiver has an on/off switch to preserve battery life. The transmitter is triggered either by a camera's hot shoe, a test button on top or an external sync cable that is not included. I used it successfully with my camera's hot shoe which was the most convenient.There are sixteen different dip-switch configurations on this NEEWER RT-16 Wireless Studio Flash Trigger that can be chosen to ensure that this wireless trigger doesn't interfere with others that may be nearby. Since my studio was no where near any other wireless studio flash triggers I used the default settings.For a reasonable price, I was able to restore wireless operation between my camera and my studio flash system with Amazon's two-day delivery.

Works great!

I just have to leave a review because I bought this back in 2019 for my einstine lighting system. I didnt want to pay hundreds for their set. Welp today YEARS later, I started having issues with the trigger and needless to say I need to get a new one BUT the fact that this 39 dollar invested lasted me soooo long, I am buying this right away to replace the old one. This is perfect on a budget and as a professional photographer of 11+ years, this is well worth its weigh in gold. Especially in this economy!

I have a name brand set up and had issues with the transmitter. I replaced it with the newer version of said transmitter. After another year or so, I had issues with that. I looked at other systems but their price tags and commitment to their "system" were too much for me after my past experience. Someone in a photography group pointed me towards these. I ordered two sets (because we all know that photographers have to have backups for those times of technical difficulty). It was nice that they were at a price point that allowed me to purchase a back up right away and it also gave me another receiver to use as well. They're not fancy allowing me to adjust my lights from my camera, but for the price, I can deal with that. The ONLY downfall that I can see happening would be the battery dying during use because you don't turn them off and you have to dissemble them to change the (button cell?) battery, but again, that's where the spare can come in handy.Definitely worth trying these.

After reading reviews I was a bit skeptical of buying this. However the cost was worth the risk. The manufacturer and some reviewers mention that although this isn't a line of sight device, obstructions such as trees may interfere with the transmitter's signal reaching the receiver, thus triggering the flash. I've found exactly the opposite. Working in a concrete building, I was able to put one concrete wall and two drywall walls, moving three rooms away, and the flash fired repeatedly. So on this point, I'd rate this product a five. As for the Instructions,,they clearly state that the transmitter has a battery chamber. "Transmitter: Slide the battery-chamber cover from the back of the transmitter and insert one 12V/23A battery (provided by manufacturer)". There is no battery-chamber cover on the back. As another reviewer pmentioned, there is an inspection sticker on the transmitter, under it there is a tiny screw. With the smallest Phillips Head I have (for camera repair) I was able to open the transmitter and see the battery. So it can be changed. Overall this is a decent product for the price. I'm giving it four stars instead of five for now. Two reasons. One: I haven't had it long enough to determine its longevity. Two: it is very strange that the instructions are wrong regarding many details. I see four channels, not the 16 the instructions illustrate. The instruction booklet is poorly written. Why do so many manufacturers in China refuse to hire educated writers for instruction booklets? Neweer, if you are going to sell in the USA, please hire someone that is capable of describing your products in proper English.

Only have had the flash trigger for one day, however, it worked liked a charm from the first flash. Trigger is attached to the hot shoe of a Canon EOS 7D camera that's paired with a Paul Buff White Lightning 10,000 flash unit. Camera is set in manual mode and I adjust camera settings from the reading off of my Gossen Luna Pro F flash meter. Could not be happier!

Great step by step instructions and it was up and running in minutes!

These saved me in a pinch. I upgraded my lighting to AB400 and bought Paul Buff triggers. The trigger from Buff broke when BARELY touched during a session. just crumbled. Grabbed these out praying they would work and bam did! I went through two Buff triggers in a few months. These have lasted me 3 years and keep going. Going to buy more as back ups. Such a great bang for your buck. I used them on my cheap strobes from amazon as well. I use a Canon 5dm3.
