Just OK, but for high standards is not sufficient (voltage-related increases to cut edges, air bubbles)

I have the film mounted in a laboratory due to poor experiences in rooms with dust in a dust-free clean bench (luckily I can use at my workplace so something after work). The dust problem could be as quasi completely off --wäre not been for the supposedly dust-free, included wiping cloth that has brought me but then at the end of some grains.

But this is not the reason for the poor review. The big disadvantage especially this film is that it is in my opinion too rigid. It adds, in particular, the camera cut to the front basically not (at least not the 3 films that I got delivered) to complete. It is always to find a more or less large bubble at the edge of the circular cutout. in some places on the edge, it stands out for no reason from (extremely cautious handled during assembly, also worn rubber gloves). All this speaks in my opinion roof that the film has too much internal stress and thus extremely sensitive to distortion (by lifting, for example, to cut / punched edges).

Say, the film works and adheres well and provided a clean room (but who is already at home ... but applies to any film), they can also be mounted relatively well. BUT: the perfect fit, is advertised with is, in place of the geometric cutouts, but factually not possible as always form in certain places withdrawals and thus air bubbles under the film. The film Mumbi way, I have previously done a better experience! I will also order me again, even if it costs a few euros more. It's worth it if you really want that you can not tell whether a film on the iPhone is mounted or not.
