I've had this flash for a long time and it works very well. The instructions leave a lot to be desired, yes, but as a photographer you can figure it out on your own. My main issue, which may just be a defect of this particular flash, is that in the very low light I encounter at events, IR is like trying to drive with a headlight lighter at night. The flash is so weak that the camera often doesn't focus and I stand still and can't take a picture. Also the flash was good but I plan to upgrade to SB900 or 910 soon as I can. If you need a good flash, this will suffice as each flash has its own problems.
