Review on K&F Concept Camera Flash - KF-570 II Speedlite with LCD Display: Canon and Nikon DSLR Compatible by Brandon Woods

I've had several cheaper macro ring flashes in the past but none came close to the quality of K&F. This macro flashlight offers too many features/options that other cheaper macro flashlights don't have. As soon as I took the package out of the mailbox, I knew from the weight that it would not be a flimsy product, I was right! I also like the locking system inside the light that locks into place on the end of the camera lens. Cheaper units simply rotate, making it impossible to use the left/right ring light option. I was also glad that this device comes with its own case. I've waited a long time for a flash like this, it was worth the wait!
