Customer Ratings & Reviews

Protecting your phone with the Zagg InvisibleShield Glass protectors, through Best Buy, couldn't be a wiser choice. From a protection standpoint, these glass screen protectors have consistently kept my device's main glass free of scratches, imperfections, and of course breaks. And if (or more likely) when the glass protector does crack (and do its job), Best Buy is always there to honor the product's lifetime warranty. Simply bring in the broken screen protector and your valid reciept and Best Buy will replace it free of charge. Great product and even better customer service. A win/win for the customer.

These glass screen protectors feel like the original glass underneath that they protect so they’re great for user experience and feel. They have a blue light filtration for eye protection and a limited lifetime warranty, which is great because they are relatively easy to crack or chip, see my photo after only a few weeks of use, but it’s better than messing up the iPhone glass underneath.

Best screen protector ive bought because of warranty. They even put the protector on for me when i swap it out at the store. Will buy all my screen protectors this way

I recently discovered the seamless warranty process Best Buy and Zag offer when purchasing screen protectors from Best Buy. In person installation was exceptionally quick and easy. Couldn’t recommend more!

My screen protector cracked and went into replace it highly recommend this screen protector

Whenever I get a new phone, the first two accessories I get before I start using it are a phone case and a screen protector. I got Zagg’s Invisible Shield XTR4 for the iPhone 16 Pro to go with one of their cases. I’m impressed with how easy the self-installation process is these days; with the applicator guide tray, it’s almost impossible to get it wrong if you follow the steps on the illustrated instructions, but if you want further support, there’s a QR code that links to a video demonstration of installation as well. The trickiest part is to clean the surface of the glass and keep it dust free prior to installing the screen protector, as despite my best efforts, I still ended up with 1 tiny speck of dust in one corner. I don’t recommend removing the glass for a second attempt though, as this rarely improves the results since introducing more dust and bubbles is the more likely outcome. Once the adhesive backing of the protector starts sticking to the glass, it basically installs itself. I just wish that the one-time-use tray were a compostable material, and not simply 100% post-consumer recycled plastic. The glass itself is composed of 30% recycled glass reinforced with Graphene making it very durable against scratches. The glass is also slightly flexible, as I was able to bend it prior to installation, however, I did not test the limits of this capability. One thing to note is that the edge-to-edge coverage only refers to the visible pixels of the display. There will be a tiny border around the screen glass where there are no pixels displayed. When used with a case, there’s about a 1mm gap between the screen protector and the case’s edge where dust and debris can collect. If using the screen protector without a case, you should be careful that nothing super thin wedges itself between the glass and screen, as this could lift/separate the glass from the phone. Since this protector has built-in blue light filtering, there is a slight bluish hue to the glass and while clear, the colors on the screen appear slightly cooler than without it. I find that it’s not distracting though and an acceptable trade-off for the eye protection this provides since excessive blue light can cause eye strain and sleeplessness. While not entirely fingerprint-proof, the surface is noticeably oleophobic and fingerprints are easily wiped off. In the few weeks that I’ve been using it, I haven’t noticed any large nor micro-scratches on it despite being in my pocket with keys and other items and frequent wiping/cleaning. Taps and swipes are responsive and register immediately, as expected, and there was no noticeable impact on performance of the front camera and facial recognition. Overall, I’m happy with the ease of installation and the protection performance of the screen protector so far. If it breaks, cracks, or chips, there’s a limited lifetime warranty so you can get a replacement; however, you’ll have to pay for shipping and handling with each claim.

I’ve gone through several of these screen protectors, and while they’ve cracked over time, they’ve done exactly what they’re supposed to do—protect my actual screen. Each time the protector took the damage, my phone screen stayed perfectly intact. What really impressed me is the warranty. I was able to get a free replacement with no hassle, which made the whole experience even better. It’s also easy to apply, clear, and doesn’t interfere with touch sensitivity. For the price and the peace of mind, this is a solid choice. Definitely worth it!

This Zagg Glass XTR4 screen protector has a lot of claims ranging from Graphene to Radiance Protection. In an already crowded screen protector space, let’s dive into the install and my week using this protector exclusively on my iPhone 16 Pro. Install was fairly straight forward. Comes with an alignment tool but not extremely fool proof. Comes with standard wet and dry wipe along with dust stickers. The mounting tool has a top and bottom and the screen protector aligns with the mounting bracket. I’ve seen other brands at much lower cost that work better so I would rate this alignment tool to be a 7 out of 10. While I managed a dustless install, there is nothing this kit will help in 100% dust free install. You wet wipe first, then dry wipe and finish with dust stickers. Then peel off backing off protector and align with alignment bracket. Dust can be introduced during this step. Nothing about this entire process is exclusive to Zagg. Doesn’t come with bubble smoothing tool but bubbles were easily pressed out after screen install. The screen protector does cover 99% of the screen as it leaves a little gap along the edges to work with most phone cases. The screen is cut to the exact length of the pixels of my iPhone 16 pro. That means that if you’re off by 0.5mm, you will get a rainbow effect on the edge of the screen protector because of how light refracts. The alignment tool isn’t fool proof so take extra care on the alignment before pressing down for the final install. As for “blue light blocking”, “11x stronger Graphene”, “nano-infused scratch protection” are all claims that I can’t prove or disprove. Smoothness feels like any other glass screen protector I have ever used. I have no way of measuring blue light reduction/blocking so I have no idea if its working. Color and clarity looks like any other protector I have used. To be honest, I can’t tell Zagg’s protector over the Spigen I replaced it with. Is it worth the $$$$ that Zagg wants for it? Maybe….maybe not.

The strongest front screen protector out there, easy to apply stays on and in place. Responded very well to touch and protection is a step above all others including blue light. Anti microbial all in one!! By far the best screen protector out there!! A bit expensive to say the least but worth it if you can afford the 16pro you can afford the best protection!!!

The Zagg screen protector was super easy to install, protects the screen well, and is holding up great! I initially tried the AT&T "lifetime warranty" protector. After three replacements in as many months, I decided to spend the money and get the Zagg. So far, so good! No scratches or cracks, despite dropping the phone a few times.

The ZAGG Glass XTR4 is one of the best screen protectors you can get for the iPhone 16 Pro, and it absolutely lives up to its “premium” label. The clarity is excellent—sharp, clean, and completely invisible once it’s installed. Touch response feels just like using the bare screen, which is something cheaper protectors don’t always get right. The XTR4 also goes edge-to-edge, giving your phone that seamless, fully covered look without leaving awkward gaps around the sides. Installation is smooth thanks to ZAGG’s alignment tray. It takes the guesswork out of applying the protector, and everything lines up perfectly with the camera and sensors. Once it’s on, it feels solid and durable. You can tell it’s made from higher-end materials because it resists fingerprints better, doesn’t scratch easily, and has a more premium feel when you swipe across it. But honestly, one of the biggest reasons I keep choosing ZAGG is the replacement plan, and the XTR4 is no exception. The lifetime warranty makes this screen protector a great investment. If it cracks, chips, or gets damaged, ZAGG will replace it for free—you just cover shipping. It takes all the stress out of everyday use. Instead of worrying about dropping your phone or seeing a hairline crack in the corner, you know you can get a fresh protector without buying a new one every time. For something that protects one of the most expensive parts of your phone, that replacement policy alone makes it worth the cost. Overall, the Glass XTR4 delivers excellent clarity, strong protection, and one of the best warranty programs in the industry. It’s a top-tier screen protector backed by a company that stands behind its products, and that combination makes it an easy choice.

I usually do not use screen protectors for three reasons. First, I am usually careful with my phones. Second, newer phones have durable screens. Third, they are very hard to put on. If they were easy, I would ignore the first two reasons and use them. Well guess what? The Zagg Invisible Shield XTR4 is easy to install. It comes with a kit that makes installation simple. The first thing you need to do is clean the phone screen. It comes with an alcohol wipe and cloth to wipe your screen clean. It also comes with a dust removal sticker if you need it. Next, you place your phone onto the plastic template. It has notches on both top and bottom. The screen protector has holes on the top and bottom where you line them up. Remove tab 1 which, flip it over and line up the holes onto the template. Press down and lift the other side of the protector to remove the film. That is it! You are done. Very simple and quick. It fits very well. I can barely see the edges of the screen protector. The screen still feels smooth as if there is no screen protector. It does not have a matte finish so the glare will be there. It has a graphene finish. I searched how strong it is, and according to Google it is up to 11 times stronger than standard tempered glass screen protectors. The thing I like best is the easy installation. I would recommend it.

The protector does everything it promises. I never have had a phone screen crack with this on it, but I have been through quite a few of them. The smallest drop or anything they seem to crack which is supposed to do instead of your phone which is great. I give it 4* simply because they are fragile, if you buy the protection plan, or are a total member it’s 5* because when they crack you get a free replacement for life. So if you buy this **make sure you get some sort of protection plan* I’ve been through 5 of them totaling probably close to 200$ which paid for my total membership already. Overall great product.

So far so good! Excellent quality - this isn't my first protector with them but it is with their higher end product. I do love the blue light filtering and the increased strength.

This has been my go to screen protector for the past few years. The blue light filtration helps a bunch with eye strain. The clarity of the screen protector is great. You can't even tell its there. The price may be a little steep but it is worth every penny. And plus if you register it you can file a warranty claim if it breaks, you have an installation issue, or scratches. 10/10 would recommend!

It did its job because it looks like my screen is fine. But the bottom left corner of the protector cracked in under a week. With the lifetime warranty I’m more annoyed at having to go back in the store than upset. I stick with Zagg specifically for their warranty replacements. Colors look good and it covers all of the usable parts of the screen. Yes, if you hold it a certain way with the screen a certain brightness/color there is a tiny bit of refraction along the edge. It’s not visible all the time and I don’t see a way for any screen protector to avoid it unless it wrapped over the edge. It wouldn’t prevent me from purchasing it.

A huge difference between this blue light shield and any other glass screen protector! Easy on the eyes, durable, great quality, fast and easy installation, and amazing lifetime warranty

Great quality. Gets replaced if you crack it. Have used ZAGG screens for years and have never had a cracked phone screen.

This was a replacement for the cheaper Zagg screen protector I had previously bought which had cracked. With the lifetime warranty, I only had to pay the difference for the upgrade. Best Buy looked up proof of purchase of the previous screen protector on my account. They offered to install it for me, but installation with the included instructions and frame were easy enough for me to do myself at home. The screen protector seals well, without bubbles, and is not affected by the case I have my phone in.

Incredibly easy installation and it provides a clear, protective cover for my new phone. Would definitely purchase again.
