The other day I did a dumb thing. I dropped my iPhone 14 Pro Max onto rough rocks.

It landed facedown.

And resulted in a crack.

Thankfully, the crack was in the sacrificial screen protector that I'd fitted as soon as I took the iPhone from its box.

It could have been a lot worse!

But this means I needed to replace the screen protector. I decided to fit an ESR tempered glass screen protector

Key features

  • Military-grade protection: This protector makes use of a sheet of ultratough tempered glass capable of resisting up to 33 pounds of force, protecting against scratches and chips.
  • Smooth and clean: The oleophobic coating shrugs off smudges and fingerprints.
  • Bubble-free: The alignment frame and cleaning kit makes fitting the screen protector quick, easy, and, importantly, bubble-free.
  • HD clarity: The clear glass means you are not compromising on display quality, and it is compatible with Face ID.

A good screen protector gives you everything you need to apply the screen protector successfully. With this ESR kit you get not one, but three screen protectors, a frame to fit it with, cleaning wipes, a nonslip mat to work on, dust removal stickers, and a microfiber cloth.

It's a really good, high-quality kit. 

Let me take you through the process and offer a few tips to help you successfully apply the screen protector.

Step 1: First, read the instructions. Yeah, I know, no one has time for that, but make time.

Step 2: Next, check to see if the screen protector fits your phone. (Check its compatibility before you buy it, but also physically hold it up and check.) This process is called a dry fit, and it's important, especially if you're removing an existing screen protector, as you don't want to end up without a screen protector.

Step 3: Satisfied that you have the right kit, remove the old, cracked screen protector.

Step 4: Clean the screen well. Even if you had a screen protector fitted, there will be dirt and muck around the edges that you need to remove.

Step 5: Fit the alignment frame around the display.

Step 6: Remove any last bits of dirt and dust.

Step 7: Remove the film covering the screen protector. Keep the adhesive side facing down to prevent dust falling onto it.

Step 8: Align the bottom of the screen protector with the alignment frame (note that the screen protector has a top and a bottom), and drop it on the display.

Step 9: Work any bubbles to the edge using a finger or the microfiber cloth. If there are any stubborn bubbles, you might need to lift the protector to get them out.
