Excerpt: For the most part, this flash has done a good job. The feature set is extensive, and the interface is very easy to use. As an E-TTL flash with my Canon 6D, results have been pretty reliable once dialed in. The flash has a lot of power, but good controls, so it's relatively easy to dial in.
Pros: Easy To Use, Powerful Output, Versatile
Cons: No Full Output As Master, Quickly Drains Batteries, Slow Recycling

Excerpt: There is a manual for this thing, but it doesn't come with the unit. You have to hunt it up from Nissin on line. When I first got the flash, it didn't seem like it was working with my Canon camera at all.
