Review on 🔮 Purple iFlight RC Rubber Balls for RC F4 F7: Effective M3 Shock Absorption Solution by Linroy Floyd

As my tests showed, this upgrade did not improve the video quality or stabilize the camera's movements as expected. The only positive thing I could say about it is that it was easy to install. However, the price is steep for such a minor improvement. Save your money and consider other options for improving the quality of your videos.
