Good quality product, good adhesion. For those who say it doesn't stick, you need to clean the surfaces well, you don't want oils from your hands getting onto the part being coated. I cleaned mine with a lint free towel and auto glass cleaner and put on chef gloves to keep natural hand oil/grease from getting on it. It is recommended to use a hair dryer to get the perfect fit and heat up the adhesive to keep it in place. 4 stars for a product that does not fully cover parts of the drone leaving
