I love these flashes. I have two for my Nikon d7200. They work well, there are no glitches with Nikon. More powerful than my sb-700. I give them a good smack. I use it for backyard wildlife and macro photography, so I get close to max burst on every shot. Mostly on camera, but sometimes I use the YN-622N-TX trigger off camera. You can google all the good things about Yongnuo flashes, this review is basically just to say I have two good units and they are holding up well.
