hit my Kindle Fire HD 7 and bought me shortly thereafter bought the antireflective film to do so. Applying the film itself is very easy and well described.
A small tip:
Making the display best only with an alcohol or the like Brillenputztuch clean. Then polish with the clean cloth available.
Conclusion:
Super product does exactly what it should and is not too expensive (as of 09/2014 7,99EUR excluding shipping charges). I myself have all the super beach vacation can test and could without any problems using the device in the sun. :-)
