The Interfit I Sync 4 has 4 independent radio channels for use where multiple photographers may be using wireless triggers such as at a wedding etc. Now you can set the channel and still keep on shooting without interference from other photographers. Each receiver has a built in light stand tread on the bottom to allow your speedlite to be stand mounted. In addition a PC sync cable and socket is included along with a mono jack converter to fit both large and small jack sync sockets for connecting to studio lighting. Runs on long life lithium batteries (included).

Used in a Nikon D-610 to fire a Vivitar DF-383-OLY of-camera flash. Works perfectly. I have no issues with function or quality of the manufacturing. One thing I would like to do but cannot when the transmitter is mounted is to use the on-board flash as a low-power fill flash. The transmitter prevents the on-board flash from opening. That's OK, I'll just get another receiver and external flash and fire two of them.
This wireless triggering device works well with my portable setup I use it exclusevly with speedlights for on location shooting. it's inexspensive compared to PWs and works just as good for my needs.
I found the performance of this sync to be better than expected. I shoot strobes manually and do not use TTL Metering connections with my on camera flashes. I needed to go light on a job and decided to use my Vivitar 285 strobes. The sync worked absolutely beautifully and I had only one misfire which was likely due to a flash unit that I didn't allow enough recycle time for. I've not yet used it on my studio strobes so I can't vouch for how well it may work with them. I will take a good guess in that they will work just as well with them. The construction may not be robust, but with care it should provide faithful service. I would easily recommend this to anyone; amateur as well as Pro - and, for the money its even better.
This was purchased for travel. My only concern is the construction which seems flimsy. So far I have had no issues with it firing, it has been very consistent.
