Bargain price. Fairly easy to fit, with care, and well-fitting. At this price, you could afford a practice run anyway. Comes with the usual scrap of fabric to clean the screen and press out bubbles.
Can I offer a suggestion re fitting? Do it by applying the protector to the centre of the screen, vertically (ie so the the first contact between the protector and the screen is a line from top to bottom, as you are squeezing the protector in your fingers and making it a U in cross-section). I find that way you create fewer bubbles and it's much easier to press them out.
