Yongnuo YN622-TX i-TTL Wireless Flash Controller & 4x YN622N i-TTL Wireless Flash Trigger Transceiver modules, all in A1 condition, all work as they should. Nikon dedicated. I originally bought these as a stopgap but they are so good I never changed them, they compete with the more expensive brands easily, fully independently controllable channels they produce superb high quality controllable flash results and are easy to use and program. Please see the photos, I could not get rid of the overhead light reflection, these units are unmarked. Please see my feedback for assurance. Having to sell all my kit, so priced to sell
