Since I bought the unit and accessories only shortly before the holiday, to me the comparison with and without screen protection is missing. One thing is clear: no not the point! Just a Mopped-Navi is exposed to increased load - and here especially the touch screen. (The?). Impairments of usability I have not determined whether it actually acts Reduces reflection, I can not say for lack of comparison (= operating without film). The attachment is indeed supported by the supplied accessories, without bubbles, I have it still do not get (the disturbed but not on). The film seems to be cut a bit short in width, but ultimately fulfilled its purpose. The price seems to me a whole to be fine.
