Best Buy Review by David
Lightweight and sturdy
The dji Prop guards are inexpensive, sturdy and lightweight.
I recommend that you buy them and keep them on for your first several flights, especially if you''re fairly new to flying a quad-copter.
They’re a lot of work to install. You must remove 8 screws; 2 screws for each motor. You must carefully keep and store the 5mm screws that you remove. Then you must carefully install and tighten 8 10mm screws, which secure the guards to the copter.
This is a routine that you simply cannot do on a regular basis. You’ll either keep the guards on, or off.
I kept my guards on long enough to become comfortable with my copter, and I’m glad I did. upon landing one time, I tried to shut the copter off with a 2-stick command. I must have done something wrong, because the copter went into reverse, and smashed into the sidewalk. The guards protected the blades perfectly.
The guards probably add a bit of weight and windage to the copter, which would reduce battery life.
The installed guards absolutely take up more room, so if you want to buy a case that accommodates the guards, you’ll have to buy a larger case.
I no longer use the guards on a regular basis, though I store them in the case in the event I may need them. I can think of a number of occasions where I’ll want to use them; flying in and under tree branches, around people and pets, and any circumstance where I might bump into something.
All said, I’m very glad I bought my guards, and they paid for themselves within the first few flights.
