DJI Phantom 4 Prop Guards are a MUST for anyone that wishes to better prevent damaged and/or broken propellers. I’ve flown hundreds of successfully DJI Phantom flights but still use prop guards. Why? My primary reason is that I land on unstable surfaces such a a rocking boat deck, etc. and the DJI Phantom often topples over after landing. Without prop guards, that would likely mean a damaged and/or broken prop. It also better protects the deck and interior of my boat from damage. Due to their quick-disconnect nature, these DJI Phantom 4 prop guards are effortless to snap off, to reduce travel bulk.
