Home/iPhone/Screen & Camera Protection/ZAGG Glass+ Screen Protector
ZAGG sells its Glass+ on toughness, and that’s exactly where it lets owners down. A large share say theirs cracked within days, after nothing more than a minor knock.
Everything else is fine: it goes on easily, the ZAGG name carries weight, and the limited lifetime warranty is worth having if you’ll actually register it and claim replacements. Whether this protector makes sense depends almost entirely on that warranty.

Version reviewed: ZAGG Glass+ Screen Protector for iPhone 17e / 16e / 14 / 13 / 13 Pro (6.1-inch) · ASIN B09C6R8JRV · Amazon US listing · no separate manufacturer model number is printed on the listing.
One-sentence verdict: Worth it if you specifically want the ZAGG name and its replacement programme on a 6.1-inch iPhone 13- or 14-class screen and you’ll use the warranty; skip it if you want a protector that reliably survives one drop, or you don’t want to deal with a claims process.
Easy to fit, harder to keep — cracking and edge lift are the recurring themes.

It’s standard full-coverage tempered glass with an alignment tray. The glass is clear and smooth, and the border is thin.
The problems are structural, not cosmetic, because for a large share of owners, the glass cracks easily and the edges won’t stay down, which is a poor combination in a single sheet at $17.34 from a brand that trades on toughness.
Clean the screen, use the dust sticker, set the tray in place and lay the glass in. Most people get a clean install.
Installing it is fine. So is touch. Coverage is full, and fingerprints stay manageable.
The edges are weak, though, both in how they feel and how well they stick. And impact durability is the headline failure, with “cracked within days” coming up again and again across thousands of reviews from owners who say it gave way after nothing worse than a minor knock.

The durability record is the story here, and it isn’t a good one. ZAGG’s limited lifetime warranty is meant to make up for it: register the protector and you can claim replacements. But that’s a process with a shipping fee each time, not a spare in the box, so whether it’s worth buying comes down to whether you’ll really use that warranty.
At $17.34, you’re paying a brand premium for one sheet, against $21.99 for three ESR sheets.
Its value depends entirely on the lifetime warranty. If you’ll register it and claim replacements, the real cost per year comes down. If you’d rather buy a cheap three-pack and swap the sheets yourself, that’s less hassle for less money. Under about $18, and only if you plan to use the warranty, we’d call it a fair buy.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| ZAGG Glass+ Screen Protector (this protector) | The ZAGG name and its replacement programme | Easy install, lifetime warranty | Cracks easily; edges lift; $17.34 for one sheet | $17.34 |
| ESR Armorite Screen Protector (3-Pack) | Cheap sheets and easy self-swapping | $21.99 a sheet, frame install | Durability inconsistent; edge complaints too | $21.99 |
| TORRAS Uncrackable 9H+ Privacy (2-Pack) | Privacy plus a spare | Full-space fit, two sheets | Privacy film dims the screen | $34.99 |
Don’t care about the ZAGG name or its warranty process? An ESR three-pack gives you three sheets for less money, and you can swap them yourself.
It goes on easily, it comes from a brand people trust, and the limited lifetime warranty is worth having if you’ll register it and claim replacements.
The durability record undercuts all of that. Across more than 41,000 reviews, the most common complaints are cracking within days and edges that lift, and that’s a bad look for a single sheet at $17.34 that sells itself on toughness. Only buy it if the ZAGG name and its warranty matter to you. Otherwise, an ESR three-pack ($21.99) gets you more sheets for less money, with no claims form.

The 6.1-inch class, meaning the iPhone 17e, 16e, 14, 13 and 13 Pro. It doesn’t fit the newer Pro models, which have a different screen layout.
Cracking within days of a minor knock is the most common complaint across tens of thousands of reviews, and it’s the main reason for the low score.
You register the protector and can then claim replacements, but you’ll usually pay shipping. It’s a claims process, not a spare in the box.
For many owners, no. Edges that lift and collect dust are a recurring complaint.
Only if you’ll actually use the warranty. Otherwise, an ESR three-pack ($21.99) gives you three sheets and no claims form.
Yes. The alignment tray gives most people a straight, centred fit.
