Query: The screen protector is useless

The case itself is ok to protect the MB Air from scratches but definitely not very strong in its material (soft thin plastic) to protect from crashes or drops. The screen protector is useless. After I put the plastic film on the screen, my wife complained it was very different comparing with the screen. We noticed some weird marks all over the protector and making the screen hard to look at... So I tore it off and threw it in the trash. I do not suggest to buy with the screen protector.
