Having used the ESR Armorite screen protector on my Apple Watch Ultra, I can share some useful tips beyond the instructions that come with the package. The box includes two tempered-glass protectors, cleaning wipes, and dust removal stickers, which are all you need for a smooth installation. First, power off your Apple Watch Ultra to avoid any accidental touches during application. Start by using the wet wipe to thoroughly clean the watch screen, removing fingerprints and oils. Then, dry it with the microfiber cloth and use the dust removal sticker carefully to lift off any remaining dust particles, as even the tiniest specs can cause bubbles under the screen protector. Next, gently peel the screen protector from its frame and align it precisely over the watch face. ESR’s alignment frame makes this easier, but take your time to ensure it fits perfectly without shifting. Once centered, carefully press from the middle outward to adhere the protector to the screen, eliminating air bubbles. One useful trick I found is to apply light pressure around the edges to ensure the tempered glass fully seals, preventing dust ingress and enhancing durability. The Armorite protector’s tempered glass feels smooth and maintains the touchscreen's responsiveness, so there’s no compromise on performance. In terms of durability, ESR's Armorite screen protector does a fantastic job against scratches and impacts, which is essential given how exposed the Apple Watch Ultra can be during outdoor use. Plus, having a backup protector included in the package is a great value, especially for heavy users. Overall, taking the time to properly clean and align the protector is key to a flawless installation. I've found ESR Armorite to be an excellent investment to keep my Apple Watch Ultra's screen pristine while preserving its sleek look and touch sensitivity. For anyone seeking reliable, easy-to-apply protection, I highly recommend giving this screen protector a try.
