I have tried many films for various displays in recent years. The self-cutting was difficult in the smartphone and I looked around for a suitable exact protector. Six pieces for an amazingly low price? Sounds perfect! And they are!
Easy to install, free of bubbles, fit, durable!
One thing I wonder, however, why six of them? Got my first film for half a year on it. The films are extremely durable! Maybe you need six pieces as selling point, who knows ... ;-)
