Hi all, mine arrived today and I'm surprised so going to ask to ensure I don't have a knock-off: is the Mavic 2 control stick protector a piece of plastic that sets over the sticks, covers the screen, but sits loose on the controller? I assumed it was going to be a friction fit of some sort over the stick grips, but mine is loose. I'll have to do something with a velcro strap or rubber band to hold it in place. Does that sound right? Sorry for the dumb question but hopefully this will help someone else in the future! Thanks for your input.
