My first step was to start looking for a suitable seller
website. Reviews from other buyers and store ratings helped me narrow down the list to a few reliable options.
Choosing a film: Protective films come in many different types: clear, anti-glare, impact and scratch protection, and so on. I decided to choose an anti-glare film so that the screen would always be readable even in sunlight.
The installation was easier than I thought it would be. The seller also provided instructions, which was very helpful. The film was the perfect size and did not leave any burdas.
