Especially big screen protectors are always difficult to assemble, anchor sets guidance and auxiliary materials (cloth, scrapers) at which make the process a little easier. Slightly less packaging would (the accessories) nice, but otherwise the product assortment is exemplary.
In conjunction with a protective case for the Nexus 7 (2013) there is an effect that the "hinges" of the protective covering in Fom of dust deposits on the protective film are visible, but the dust is very easy to wipe off - this is a principle related problem, the would probably occur without protective film.
The films are very precisely cut and fit exactly (half a millimeter less at the outer edge would have my life in rearing eventually made a little easier).
Conclusion: a good product!
