I purchased this after I had my drone hit a low hanging thin branch, thin being the important part. After replacing and arm and 3 props, I decided to start looking around. I originally bought another type that unfortunately covered the LED's on the H as well as the motor vents. It went back, then I saw this one. It is harder to put on and take off so I simply keep it on except when traveling. It works just like shown on Y**tube. Also a lot cheaper than an arm and 3 props. :-)
