Pros & Cons
Pros
New: if you remove them, reinstall the original screws and now the screws that come with these prop guards. They are a must if there are any cars or animals that could be injured by a falling phantom.
Cons
I want to see something that clips on and off and doesn't require to take apart the motor mount and screw directly into the motors. I replaced these with the blue larger sized dji guards designed for the dji phantom 2.
Plastic material is not durable at all. They also stick out a little too far on my phanton 1. Props stick out beyond protector. One slight bump and they break.
Cons: creates noticeable decrease in agility and more drag in the wind. They are too small and propellers hang off another inch or so.

Highlights
Quality
Caution with the string you thread through the guards to protect the propellers from branches!
Only work with the original phantom 1 props, if you are upgrading to the phantom 2 props, you need to get the larger prop guards.
Packaging/appearance
Do not reuse the screws after removing the prop guards!

Fit my dji 1 broke on first crash but thats what they are there for and also why they are cheap.

They do protect the blades pretty well, but they are not very strong.

They do not fit phantom 3 but they are good quality.

They are slightly longer and without the guards on they will screw into the motors killing them.

Saved my drone from brutal tree damage, that possibly could've destroyed my entire phantom 1.

I only gave 4 stars because they do feel just a tad flimsy.

Anyone buying this remember if you take them off use the original screws so you don't kill your motors.

The right size for the stock blades, add the 10 blades and they're too small.
