Totally agree. I've now purchased 2 WSKEN, each came with 2 protectors in the box, so I've attempted 4 installations and all had air bubbles I couldn't get rid of or dust under the protector no matter how hard I tried. So I absolutely gave up. Tried the Torras and it worked brilliantly.WSKEN was terrible for me, both installations. Bought the Torras, hoping that’s better.
