The protector was easy to apply. The backing film comes off easily because of the tabs fitted on to it - with other products I have used I seem to spend hours trying to remove the film.
A quick clean of the screen with the cloth provided, and the protector just sticks in place. Then smooth down with the side of a credit card, and the job's done. Initially there was one bubble left, but this disappeared after a couple of hours.
The protector is very clear, so the screen is as bright as if the protector was not in place.
With the protectors being only a couple of pounds each, they seem to be an ideal investment for any camera that they fit.
