Class part! Better than any film

I can only recommend a real glass lens. If you take some time and the cell phone screen thoroughly cleaned, the disk sticks almost by itself. The best way in the bathroom, the shower a moment to run hot until you stand in the mist. Then one has little dust in the air and under the disc. Fit washer carefully, but do not press. Then you can still move. If it is really easy to press with a finger in the middle and watch as she sticks themselves.
