If we don't like it or it is damaged, is it easy to remove?

In case you dislike the look, we highly recommend holding the material up to the glass prior to actually installing it. If installed and it gets damaged, yes it is easy to remove. Peel away the film from one corner and pull the film from the glass. If any adhesive remains on the glass it can easily be removed with a spray of soapy water and a single edge razor blade. Blades cannot be used on plexiglass or polycarbonate sheets to remove film.
