I was looking for a cheap protector for my S4 Mini and ordered me it here. They came after about 4-5 days with me and after 5 minutes, the film was on my phone. The film consists of 2 superimposed layers, which on the one hand helps that it is harder and more resistant and it simply sticks. I have already used 2 sheets and could find not a single bubble in both. Also they were right the first time firmly and accurately. Would I get me again at any time!
