Most reviews are true. Using a pen is sufficient for this. It is very easy to put on and take off. I tried it for a month until I finally stopped taking it. Wow my screen looked so much better I'm having a hard time putting it back on. The good thing is that it is so easy to put on and take off that you can put it on when using the pen and take it off when watching videos or for everyday use. There are no scratches yet, the pen has not been erased, but again about a month has passed.
