When searching for a screen protector for the Z30, I finally opt for this copy because I intended to take no for Cheap. For other phones, where I had a cheaper, there it was not possible to apply without bubbles. This is not the case with the film. The film comes in a high-quality packaging with lots of accessories and instructions. Using the Blasenentferners (similar to a credit card) I've managed to stick with no bubbles. Even dust particles can be removed with a supplied adhesive tape. Another advantage is that they can be washed off with water and can be applied again. Perfect fit is of course!
