Considering how much mobile phones cost these days, it can be really frustrating when their screens get scratched. Fortunately, there are a few mobile screen protectors out there that can ensure this doesn’t happen. Here are a few of the options available, including how they stack up against one another.

Tech Armor

Tech Armor sells many phone and tablet accessories, but their ballistic screen protectors are one of their most well-known products.


  • Free Shipping in the U.S.-You can get your items shipped to you for free provided that you live in the U.S.
  • 99.9% Clarity-The site claims that you can see through the screen protector so well as to make it nearly invisible.
  • Fingerprint Resistant-The Ballistic Glass products for Tech armor resist smudges and fingerprints more than the mobile glass does, according to the site. The protectors are also supposed to be smooth to the touch, preserving the glass feel you get from the bare phone.
  • Lifetime Warranty-Tech armor claims that they will replace any screen protector that gets screwed up during installation, or that gets damaged along the way for free. The shipping may or may not be free for the replacement.
  • 30 Day Refund-If you just don’t like the purchase you can send it back for your money back within 30 days of purchase provided you didn’t do anything with it yet.

Invisible Shield

Invisible Shield is a popular line of screen protectors that are known for their durability.


  • 100 Durability Score from Review Sites-At least one review site gave Invisible Shield a 100 out of 100 for durability. Tests included being shot with an arrow, being dropped onto a bunch of rigid nails, being burnt in a fire and even being blown up in by explosives. None of the dangers made it past the protector.
  • Military Grade-According to the site, the components are used from 3x shatter protection materials used by the military, which were designed to keep military helicopter blades safe.
  • Self-Healing-The Invisible Shield products use nano-memory technology to allow your protector to actually heal scratches and dings after they occur.
  • 3X Shatter Protection-The site says that the screen protector will make your screen three times more resistant to shattering, and this seems to be at least somewhat backed up by independent review sites.
  • Wide Range of Phones-You can also get products for LG Nexus 5, the Galaxy Note 3, the Droid Maxx, the LG G3, the HTC One M8 and the LG G2 with the HDX line.


Zagg also produces cases that can serve as screen protectors.


  • Variety of Colors-The color choices will vary based on the case, but the Galaxy S5 has white, red, pink and blue for case screen protectors.
  • 4x Stronger than Screen-The case itself is a screen protector that’s 4 times stronger than your screen. The case is designed to handle shock resistance, protection against breaking while still maintaining touchscreen sensitivity.
  • Resists Splashes-The case can resist full splashing and spills, and can resist dust getting into your phone in a way that skin only screen protectors really can’t handle.

Head to Head


Tech Armor costs $16 or so for their Ultra Clear Ballistic Glass offering for the iPhone 6. The cheapest is the Ballistic Glass Screen Protector for iPhone 5 which is around $10.  

The Apple iPhone 6 HDX is $25 from Invisible Shield. The “original” design is $15. The “glass” maximum clarity and ultra-smooth product is $35 or so. If your goal is just some protection with as little interference as possible, the glass version is the one you want. The other lines including the HDX are the ones that have the military grade protection.

Zagg cases start with the Arsenal Case for iPhone 5s which protect screens for just $50. Just about all screen protector cases including the ones for Galaxy S5, iPhone5C and iPhone6 are $50, with the exception being the perimeter case for iPhone4 which is only $20, but it only travels around the outer edge.

This means that Tech armor is cheaper than Invisible Shield in general, though Invisible Shield has a wide price range depending on which product you prefer. Zagg products like Arsenal are going to be the most expensive of the bunch since the material is harder in case form.


Tech Armor currently has screen protectors for iPhone 6, iPhone 5, G3, and Galaxy S5. The protector is oleophobic, which means that it resists oils meaning fingerprints and smudges won’t happen as often. The protector can’t heal it, but it will resist scratches. Review sites say that it could resist hammer blows, and even efforts to cut it with a penknife. So chances are good it can handle keeping your phone relatively safe in your pocket. Some experts say that it’s important to be careful not to the sticker tab off since this is what keeps the layer ready to be placed on a phone.

Invisible Shield features vary between 93% clarity for “original” lines to “100%” for “glass” lines according to the site. The HDX line is a little more expensive, but it features military level durability so if your concern is keeping your iPhone safe at all costs, the HDX is a good way to go.

Zagg cases do mobile screen protection by completely enveloping them in a case. This means that these products, like the arsenal, are going to be the most durable you can get in an absolute sense. The Invisible Shield products are the most durable in terms of something that’s more invisible and that preserves the initial feel of your phone.

The advantage of Zagg products like Arsenal is that they tend to create more of a complete seal around your phone so they are better for keeping out dust and grit. They are also considerably better at sheer resistance when it comes to physical damage. After all, the case is more likely to break first before your phone does since the two objects are more separate. With a second skin approach like from Invisible Shield or Tech Armor, anything that punctures the skin is likely going to also cause damage to the actual phone itself.
