Drone for photography?

[SkyCapture]

Hi everyone,

a friend and me work as freelancing-photographers. We especially shoot on big city-events. And of course there are a lot of angles we are not able to reach.

Now we are thinking about buying a photography drone.

Something like this:

or this:

Do you have any experience using them? Are they worth their money? How much do we have to invest to get real good results? (We have to keep them in the air for about 20 minutes average / we need calm flights) And can you recommend any products please?

Thank you all!

Unfortunately I personally don't have any experience with them, but I know of them. Controlling them (and trusting them with your photo gear) are the obvious issues, but I would imagine there is a definite learning curve in mastering photography from one of these things.
