Zagg InvisibleShield Screen Protectors Review – Sapphire Defense vs Glass+ vs VisionGuard

If you’re looking for screen protectors, Zagg’s InvisibleShield Screen Protectors might not be for you. Don’t get us wrong, Zagg’s InvisibleShield Screen Protectors do help from day to day scratches but that’s just it. Aside from keeping your iPhone scratch free, the price of a Zagg screen protector isn’t really worth it.

Out of the Zagg InvisibleShield Sapphire Defense, Glass+, Glass+ VisionGuard and Glass+360, we’d go with Sapphire Defense. The InvisibleShield Sapphire Defense is one of the toughest screen protectors we ever used. But it does come at a higher price tag.

At Mobile Reviews Eh!, we do reviews based on actual usage. We do tests and use the products for days and maybe weeks. When it comes to screen protectors, we have to use them. And break them. And then add them to the collection of other glass weʼve broken over the years.


If you like how we do our reviews, please consider buying the products on the links scattered on this article.

Zagg InvisibleShield Glass+ Review

Zagg InvisibleShield Glass+ is Zaggʼs base model of glass. Thereʼs nothing really special about Zagg InvisibleShield Glass+ except that itʼs overpriced. Since there isn’t anything special about the product, Zagg had to include a bit of marketing fluff on the 9H hardness of the glass.

We’re always skeptical about the actual hardness of a screen. The glass ~may be of 9H hardness but the coating that goes on top of the glass isn’t. All the minor scratches that show up on your screen is most likely scratches to the coating. And since we can’t separate the coating from the glass, well, we can’t tell if the glass is actually of 9H hardness.


Installation of the product is quite simple though it takes a tiny bit of guesswork evenwith the EZtabs. Thereʼs no tray and definitely no easy install tab pull tray like Spigen has.

The Zagg InvisibleShield Glass+ has a standard fit. It covers the viewable area of the iPhone and thatʼs it for 40 bucks. Youʼre not even getting name-brand recognition since itʼs just a piece of glass.

RECOMMENDATION: If youʼre looking for a better alternative to the Zagg InvisibleShield Glass+, check out some of the products from FloLab. Weʼve been using their products for months now and the overall quality is a step above products that cost more.

Zagg InvisibileShield Sapphire Defense Review

Zagg InvisibleShield Sapphire Defense is a screen protector infused with sapphire crystals. The sapphire crystals apparently improve scratch resistance and also makes the screen protector incredibly tough. The box also says that the Zagg InvisibleShield Sapphire Defense offers 7X more shatter protection against an unprotected screen which we’re guessing is because of the infused sapphire crystals.

To test this claim, we dropped a 200g steel ball on it. We did a similar test with liquid screen protectors before and we figured out that a normal tempered glass screen protector breaks at 14 inches in our crude screen protector testing unit.

The result was shocking. Zagg InvisibleShield Sapphire Defense didn’t shatter from a 4+ feet and would only crack after being struck by a hammer.


We do have to point out that the improved scratch resistance is probably not true. We took a coin to the Zagg InvisibileShield Sapphire Defense and was able to scratch it easily so we put the hardness of the product between 4-6H.

When it comes to installation, Zagg includes a installation tools called the application squeegee. Honestly, the squeegee is only there to make you feel better that youʼve spent an extra 10 bucks on this screen protector because we donʼt think you need it. Thereʼs also no tray on the installation kit but the yellow tabs are quite useful in helping you align the screen protector to the iPhone.

The Zagg InvisibileShield Sapphire Defense only covers the viewable area of the iPhone. This means the edges of the device are going to be left quite exposed. Take the fit of the Zagg InvisibileShield Sapphire Defense into consideration when you pick an iPhone case.

The edges of the Zagg InvisibleShield Sapphire Defense are also quite noticeable as they are not rounded. In fact, the edge of the Zagg InvisibleShield Sapphire Defense product seems rougher than the standard Zagg InvisibleShield Glass+. Zagg InvisibleShield Glass+ edge looks rounded and polished, the Zagg InvisibileShield Sapphire Defense does not.

After putting the Zagg InvisibleShield Sapphire Defense  through our impact tests, we’ve come to realize that the reason why there’s a sharp edge is due to blend of plastic and glass in the product.

Zagg InvisibleShield VisionGuard Review

Zagg InvisibleShield VisionGuard has a special feature that protects your eyes from High Energy Visible Blue Light. The blue light is apparently very bad for sleep and contributes to digital eye strain.

At the end of the day, Zagg InvisibleShield VisionGuard is probably the fluffiest product out of the 4 that weʼve used. It’s almost impossible for us to determine if the feature actually works. The only way to test this claim out is to put this on every screen we have because honestly we use our iPhone the least. There are way too many variables to figure out if this claim works.

When it comes to fit, the Zagg InvisibleShield VisionGuard is case friendly which means itʼs going to work well with whatever case you decide to go with. The glass has, from our perspective, a 2.5D fit as you can still feel the edge. But itʼs smooth, unlike the Zagg InvisibleShield Sapphire Defense. The Zagg InvisibleShield VisionGuard extends past the touchable area of the screen which isnʼt the same as the Zagg InvisibleShield Sapphire Defense or the Zagg InvisibleShield Glass+.

This is actually worth noting because the Zagg InvisibleShield VisionGuard is going to offer ~that much more protection for your iPhone when compared to the other Zagg screen protectors. More coverage, more protection. For first time drops anyways. The Sapphire Defense is still going to be better after repeated rops.

Installation is simple as Zagg includes a plastic guide to ensure an accurate install. The Zagg InvisibleShield VisionGuard, like all of Zaggʼs products, will hold up well against scratches from day-to-day objects and we didnʼt have any issues with bubbles or the edge chipping from our fingers.

The big question that we had when it come to this screen protector was “Will it change the look of the screen on an iPhone?” The packaging says it preserves the true colors of your screen. In reality, the answer to that question is: we  have no idea. We canʼt see a difference on the OLED screen of the iPhone XS Max. The glass does have a blue tinge but did it make our images look warmer? Not really.

Zagg InvisibleShield Glass+360 Review

When we first got all the screen protectors, we thought the Zagg InvisibleShield Glass+360  was the same as the regular Zagg InvisibleShield Glass+ but with a crappy bumper. We were wrong, itʼs a edge-to-edge screen protector with a crappy bumper.

The Zagg InvisibleShield Glass+360 seems to play well with cases from our Top 10 cases for the iPhone. And thatʼs a good thing. But do realize that you’ll be wasting the other parts of the Glass+360 if you use it with a case. Other than that, Zagg InvisibleShield Glass+360  feels like the standard Zagg InvisibleShield Glass+, no bubbles, holds up to scratching from day-to-day objects and the edges seem solid enough.

The Zagg InvisibleShield Glass+360 also comes with two other things which is a back protector and a bumper.

When discussed piece by piece, the back protector offers little protection and smooth. So smooth that the back becomes a wet bar of soap.The bumper, on the other hand, feels incredibly cheap. Itʼs thin and doesnʼt feel like it would offer your iPhone much protection. The kick to the iPhoneʼs face isnʼt the thin and cheapness, itʼs the tackiness.The bumper feels like a rejected Alibaba discount. Honestly, youʼre better off buying a regular glass and getting a Mous Clarity for the same amount.

When compared as a whole product, the screen protector is nice but itʼs nothing special. The back protector has no additional texture but adds a bit of protection for the back of your iPhone. As for the bumper, it’s amazing in the fact that the iPhone buttons are tough to use.

Overall, the Glass+360 is a poor product. The glass isn’t bad but the bumper and the back protector are terrible. Why would anybody cover their $1600 iPhone with such a bad product?
