I originally had a Nikon SB600. Unfortunately, I left the batteries in for an extended period of time and that was that. Rather than send it back to the manufacturer for repairs I did a little research and saw a few (new to me) manufacturers of similar flashes. After reading reviews of trusted sources I opted for the Neewer unit. The Nikon flash I had owned for sometime and used under varying circumstances (eg. room full of people with lower ceilings to factory location with 20 ceilings and depth of over 80). So far the Neewer flash seems to do just fine although I have found some shots to be under exposed. (*This could just be me as I have only used it in a couple of projects.) I will be testing it more in the future. Important: I think I should mention I am not a Pro shooter. I have been an art director and creative director in several ad agencies for over 20+ yrs. and hired many photographers and served as AD hundreds of times for stills and broadcast video. As a result I have become a pretty good amateur photographer. I usually shoot with a Nikon 7100, Sony a6000 and occas. studio lighting I own.
