Review on Ultimaxx High-Power Automatic Flash With LED Video Light For DSLR Cameras With Standard Hot Shoe Compatible With Canon, Nikon, Panasonic, Olympus, Pentax, And More by Nathan Pintac

I ordered this flash three times. The first two didn't operate correctly (wouldn't charge up, wouldn't flash, etc.). The seller was good to work with, and we finally got one that was operational. Unfortunately, the light output doesn't match the guide numbers. If you are using this in small rooms where the light bounces around a lot, you can probably get by with it. According to the description, it should have been just what we were looking for, but in use it left everything underexposed.
