A Drone Landing pad is great when there is long grass, sand or a gritty surface that you don't want blowing on the drone when taking off or landing.
Also good for people to know where the pilot of the drone is.
This is the one that I have. It folds up into a small bag... See me fitting it back into the bag here.

A camera cleaning kit ... for a drone!?
Camera cleaning kits are great for not just cleaning the camera of your drone but also cleaning (Or blowing) dust and dirt from the drone itself.
I can't justify the cost of one of these but if you want to be able to use your drone without a phone then this is the way to go. I have read good things about this but until I make a million from this website (Don't laugh, I've made about £15 so far this year!) then I'll stick with my phone.
It isn't common but lithium battery fires do happen, so this is a must if you're worried about this.
This drone accessory keeps you and your device safe in a fireproof bag, also useful when travelling on an aircraft, although I have never had this stipulated when flying.
