Prioritise an exact model cut, full adhesive, rounded edges and an alignment tray. Glass thickness and “9H” matter far less than listings suggest. Spigen and ESR are sensible mid-range starting points; Ailun and JETech for budget; Belkin and ZAGG if warranty terms matter to you.
The features that matter
| Feature | Why it matters | How to spot it |
|---|---|---|
| Exact model cut | A protector cut for a different phone lifts or gaps | Model list in the description |
| Full adhesive | Prevents air gaps; keeps in-display fingerprint sensors working | "Full adhesive" or "fingerprint compatible" |
| Rounded (2.5D) edges | Less chipping; nicer to swipe over | Edge description or close-up photos |
| Oleophobic coating | Smears wipe off; wears over time | Water-bead photos; reviews after months |
| Alignment tray | Straight fit first time | Tray or frame in the box |
| Thickness | Thicker isn't clearly tougher; can affect case fit | 0.3–0.4 mm is typical |

Where the money goes
Paying more tends to buy a better tray, tighter quality control on cutting, and sometimes a replacement scheme. It doesn't reliably buy harder glass. Our cheap vs expensive page goes further.
Questions people ask
Is thicker tempered glass better?
Not necessarily. Very thick glass can clash with cases and in-display sensors; adhesive and fit matter more.
Are expensive tempered glass protectors worth it?
Sometimes, for better trays or warranty schemes. The glass itself is often similar.
