Review on Yongnuo YN 622N TX I TTL Wireless Controller by Non Martin

Easy to use and excellent performance. I use it on a Nikon D750 with two SB-700 flashes, each with its respective trigger set in a soft box. A special feature of the D750 is that the hot shoe has slightly different specifications than other Nikons. The hot shoe on the camera is a little lower than usual. This will result in the device not working if not properly aligned. A VERY simple problem: put the transmitter back on, turn the locking ring until the pin pops out of the pin, pull the trigger very slowly and gently until you hear/feel the locating pin click into place. I haven't had a single misfire in the several hundred shots I've used to date.
