I have a Blitzgäret searched for my EOS 550D welsche not as expensive but has many features. Then I saw the Neewer TT680 and read good reviews. Ordered and get unpacked plugged into the camera and tried. Bin to get very excited about the blitzgäret, you do not have 300 or 500 to spend and good lightning. I'm going to him against BUY. He also works great with my new Eos 70D.
