I buy for years only by sheetsFoliX and am satisfied with this film. The application manages quite easily because the checkered Protector makes life very easy. The Dust Remover is a useful addition, but could be larger and be a little less strong adhesion. The curvature of the front glass makes the film manufacturers life any easier, but I think you get the good solution. Film for the back is in three parts, but the manufacturer is offensive to the topic and sets an alternative solution at. On criticism and questions will be responded promptly and it gets to the customer feedback, greatly to be praised.
