Review on Feiyu Tech G4-QD: Quick Dismantling 3-Axis Gimbal for GoPro Hero3, 3+, 4, and other similar action cameras by Katrina Brown

Great stabilizer when not vibrating. For some reason, my stabilizer and other Feiyu-Tech stabilizers vibrate when held at acute angles and when I have filter lenses installed. I contacted feiyu's technical department and sent them pictures of my installation and a video of the problems, but they had no explanation and suggested that I update the software. It didn't help. If I didn't have a filter (just a few ounces) covering my GoPro camera, there would be no vibration. would give 5 stars for that. Of course they update them every few months and the new ones probably fixed the problem. If you've never used a gimbal, get one! Completely changes the quality of your videos from choppy to super smooth.
