Unfortunately the is not so. The films are inferior, considering that one gets an expensive wants to protect it.
It took me several films at a general tidy to get up (no wonder that one gets the same 6 pieces).
I then still what brought me by the company SWIDO. Although these are more expensive and contain only two pieces, but they are much easier to install, extremely high quality and still have some other good properties (grease resistant and non-reflective, etc.).
Conclusion: Better access to another product, cheap just has too many disadvantages;)
