Pros:* Adds protection for your propellers* Easy to install Cons:* Relatively heavy and increases drag* Speed is halved* Flight time is halved I bought this for my first drone so maybe it's my inexperience , but I was surprised to find that after installing these guards on my DJI Mini 2 in normal mode, the flight speed was reduced from around 22 mph to 10 mph and the flight time was reduced from 20 minutes to 10 minutes. I burned 50% of the battery in 5 minutes before flying home and taking it off. I will use guards where required by law but other than that I will never use them on normal flights, they are literally too annoying.
