Spigen SGP's Steinheil films have been among the best iOS screen protectors we've seen recently. It's now updated two of the lines in the family to fit the iPhone 5.
Overall, I am extremely pleased with the Spigen SGP Steinheil Ultra Oleophobic screen protector. It is so easy to apply, and it looks great once it is on. This protector can go toe to toe with the Zagg Invisible Shield and easily win.
The result is my current favorite way to protect my iPhone– an SGP Leather Guard on the back, an SGP Steinheil screen protector and side films and a black Apple bumper.
Even though these are hard-style films, once applied the difference is minimal, and it's hard to see any loss of screen brightness or feel any loss of sensitivity
