I like how easy it is to use, and can be customized so easily! It's also very secure for our business needs. Nothing in particular - it works great for us with all of our projects we are working on. We have used propellor to help gather information about various construction sites around town.
They will fly over those areas at regular intervals (usually every hour or two), take pictures, and return them back to the server. This has helped tremendously by allowing us to get up-to-date photosβ¦
