These propeller extensions are a must-have accessory for any drone enthusiast. They were easy to install and provided excellent protection for my drone`s delicate parts .The additional length made flight smoother and the unique design offered exceptional stability. The only DRAWBACK was that the product's instructions were not completely clear, but the installation process was intuitive. Overall, a great investment for anyone looking to improve their drone's performance. Don't hesitate to add these electronics to your video camera collection!
