The film fits perfectly on my SLT-A55V (as expected). The film itself makes a robust impression and could be easily muster. Tip: breathe on the display briefly and then applying the foil - that facilitates Strip out the air bubbles. I had immediately after assembly even smaller "block noise" that had disappeared but the next day (probably had the moisture under the foil still evaporate). The film is now virtually invisible.
I naturally can not say anything about the durability.
