Of the 3 protections, the 1st was therefore taken as failed for a test. I properly the other 2 of 2 Iphones 4. No squeegees so be aware used his finger (thumb) to remove bubbles. There may be a mark on the protection (that of the blank around the earpiece and the camera). Indeed this cut remains in the product packaging and creates a slight mark on the protective film. By cons at this price do not expect quality. I do not know how protection are in others, but then after 2 months, the film is dirty (fat) quickly and traces of micro scratches on the film appear. Visible with artificial light.
