I continue to use my Phantom 3 Standard almost daily.
I just recently purchased Litra Drone leg mounts for attaching cube lights to the legs of my P3S to do light painting. With the cube lights attached it reduces my flight time by about 4 minutes overall because of the added weight.
It amazes me how my P3S which is almost 5 years old still flies just as well as the day I bought it. Thanks to the addition of third party software and the availability of 3rd party batteries, it is still relevant today. My Spark is newer, more stable when landing (has VPS), has more satellites, has newer tech and is a great drone but it will become obsolete before my P3S because there are no 3rd party batteries available for it and batteries are now very expensive and difficult to find, so once my current 3 batteries are done that will be the end of the Spark.
