Summary: I took this out of the box, put in batteries, put it on my camera & it worked great. I used it again 6 weeks later and all was still good. Another two months I got it out again & it was dead. I put in fresh batteries and nothing. Dead as a hammer. I have since bought (and returned) 3 different flashes that didn't work as well as the pop-up flash on my camera. I have talked with 4 different technical support people. UGH! I'm very frustrated.
Summary: It's true you get what you pay for. This flash washed out all my photos - even when I had the flash pointing straight up. There's no way to adjust the power of the flash (not that I could find.) I couldn't return it fast enough.
Excerpt: The first flash lasted 10 days before it stopped firing. The replacement lasted just 2 days before the same thing happened. [...] I would definitely buy from Adorama again, just not this flash.
Excerpt: Have only used a few times during the holidays, so maybe I am missing something I will find in the instructions now that the most hectic time of year has passed. Exposures have been good with flash pointed directly at the subject, but underexposed with any kind of bounce flash, including with the reflector card (just a piece of cardboard) included with the flash.
Pros: Durable, Fast Recycling, Lightweight, Powerful Output
Excerpt: Finally, there are choices! Vivitar has finally provided digital flashes to compete with the OEM guys. This flash is a steal compared to the NC units. Great modulation, no overexposure, and good overall performance.
Pros: Consistent Output, Easy To Use, Powerful Output
