The application is a little different from other screen protectors (no 2 protectors per page which are deducted consecutively) but is without blistering possible or can the bubbles are then deleted out. The films are lucid and accurate to the surface of the Smart 4 Turbo.
The only negative is the surface finish of the films: Each fingerprint / other dirt remains immediately (to clean) clearly visible on the slides, also form comparatively light scratches, which no longer can be removed also. Since these two criteria are very disturbing highly conspicuous and just in bright light, I rate the films even with 3 stars.
