I have seen many Tempered Glass (TG) tested products. Since I had bought by chance a trial for my former smartphone (Nexus 4) a TG screen protector and was insanely zufriden, I converted in our household all possible display films on TG (mobile phones, tablets, etc.) This product forms for my quality scale, the bottom drawer from. Despite (MMN) sufficient experience in applying screen protectors and TG-products I did not manage to get this product without bubbles on my Nexus 9.
Only positive aspect: After complaint, returning without hesitation I got the purchase price refunded.
Only the question why the product could not be reviewed here (has indeed now changed) went unanswered.
