They serve their purpose but make transporting your quadcopter a bit of a pain.

They serve their purpose and are very durable, but you won't use them much. I bought these to prevent rotor damage to my quadcopter (DJI Phantom 2) while learning to fly it. Well, learning to fly it was incredibly easy. After the first hour, I saw no use in keeping them on, however, I did for another couple of flights. Only complaint I have about the guards is that it significantly affects how you can transport it. If you own a molded plastic case, it won't fit. If you transport it in your car, you would need nearly double the space you would need without the rotors on. Just take them off to transport, you say? That's all you, buddy. That's 10 minutes I would rather spend flying the thing.
Now, if DJI would only make the drone as sturdy as these. My Phantom 2 had a microchip spontaneously melt upon start-up. It is currently at their facility being repaired. No, I never crashed it, nor tinkered with it - the microchip just caught fire and melted. LUCKILY, it was on the ground (during start-up) when it happened, so it still looks brand new. Just hope it doesn't happen again when I get it back. If it does, let's hope it happens while on the ground again.
