ZNitro Glass Screen Protectors

We were sent these tempered glass screen protectors from ZNitro to review. ZNitro cases are claimed to be Hammer Testedâ„¢, scratch proof, resistant to smudges and fingerprints, and have superior hardness.

Here’s a video that shows how to apply, and shows the hammer test as well as its scratch resistance.

I did not do the hammer test on my phone. I did place the protector on my phone to see how well my finger could glide over the screen, and found that to be smoother than the current protector- which is plastic. My phone is different from the style provided to us(iPhone 6 and iPhone 6 Plus), so I did not try applying it.

There are mixed reviews on Amazon about these screen protectors. Some have found that they chip and crack easy(but they have saved the phone’s screen. One person replaced the product 4 times in six months and paid $12.99 each time with the warranty ZNitro provides. Several people complained that the screen interfered with some phone functions(calls were muted, light sensor, etc.), but that could be due to improper fitting on their phone. Others had no complaints at all.

The screen covers come in a variety of colors for the iPhone and Galaxy S4, but for the S5 and other styles of phones, it is limited to clear, black, or white. Most screens run at about $39.99 on the ZNitro website. You can also opt for a privacy screen on some for $10 more. Amazon.com seems to be selling these for around $20.
