Always use one, since I managed to get a nasty scratch on the dash of a BMW. I've no clue how it got damaged, so since then I use a Speedo Angel film...
What type do people tend to go for: Nano Glass, Anti-Glare or Ultra-Clear? I fancy fitting one on my 899, but can't decide which type.
Fitted angel on the monster Dec 2018 still there, a little bit of crazing on the surface. But still protecting the display screen effectively. I still have a spare which as of yet, I have not needed to fit.
