Tech21 Impact Shield ($35)
Next up is the Tech21 Impact Shield for the Galaxy S9. They're a brand we know, use, and trust when it comes to cases. They've also offered some pretty great screen protectors in the past.
However, we're not yet sure if the Impact Shield is a film or tempered glass. Coming from Tech21 we're pretty confident that it will keep your phone safe, but the site doesn't say, specifically.
Either way, Tech21's Impact Shield is extremely clear, durable, scratch-resistant, and uses three layers of "bulletshield" material used in bulletproof glass. That's impressive. At the same time, the protector is only 0.03mm thin with perfectly curved edges to retain touchscreen sensitivity. All of that for less than ZAGG or Otterbox.
