Let's start with the disadvantages. I have a very large carrying case for my DJI Mini 2, it takes up 65% of my carrying case. Only one of them vibrates during flight, but does not affect flight. Pros: I crashed really hard with them (3 times) just to push them to the limit and I know without them my props would end up in the trash and possibly a broken arm or gimbal! Seriously, they let you get really close to everything without having to worry about it because it saves you on replacement parts or the time it takes to send them in for repairs. Yes, they activate the payload and the flight time is reduced to around 23 minutes, but the shots are worth it and the protection gives you peace of mind!
