Amazon カスタマー 2 The setup worked for the first couple of times with no problems. However, after extended use in the field, the clip that attaches to the camera uses a flimsy spring that can dislodge the receiver from the camera hot shoe. If you are in the field, the spring is hard to find if it lands in any vegetation. Several times my tripod or other gear snagged cable on the receiver became detached from the camera. During last photo shoot both transmitter and receiver were on but there was no recording on the camera. I couldn't afford a Rode wireless mic system, so bought this brand. In the end, I ended up buying the Rode system, which has worked flawlessly thus far. Will keep the Synco system as a backup or spare. Should have bought the Rode system. Although expensive, I could have saved a lot of money if I had not been so cheap.
