SuperShieldz Tempered Glass 2-Pack
Another reputable brand is SuperShields, and they're offering a 2-pack of durable glass for one low price. The idea here is you have two in case one install goes wrong, or if for some reason one breaks. Basically, you'll have an extra for any scenario.
Supershieldz makes some of the most durable glass around, which is why they offer a lifetime warranty. You'll get two pieces of 9H glass with a 99.9% clarity rating. They also add an anti-fingerprint, scratch, and oil coating to keep your screen clean and safe.
This glass is 0.3mm thin, so it's a little thicker and more durable than others on our list. You'll still barely know it's there, but that's something we wanted to mention. Additionally, they offer films if the glass isn't your thing.
