Property me 3 sets this remote trigger for my external flashes (1x Nikon SB 910, 2x Yongnuo YN-560 II) purchased and am thrilled. Since I almost exclusively take pictures in manual mode - with both camera and with the flashes - are these triggers optimal for me. After about a month ago and about 2,000 trips without a misfire, I can say that well. As i-dot came about that, contrary to the image view from Amazon and some negative reviews but still have such a switch due to a lack of In.- off switch the transmitter supplied. The newer Verion RF-603 came to me out of the question because I do not want to miss the tripod socket of the recipients and the sender seems to me too clunky. Absolute buy recommendation
