Short answer
Pay more if you want a better fitting tray, a replacement scheme you'll actually use, or special coatings (anti-reflective, privacy). Don't pay more expecting harder glass: budget tempered glass is usually similar. For older and cheaper phones, a budget multipack is the sensible choice.
What extra money buys
| Feature | Do you get it? | Note |
|---|---|---|
| Alignment tray quality | Often | The biggest practical difference for first-timers |
| Cutting accuracy and QC | Often | Fewer off-centre or misshapen pieces |
| Replacement scheme | Sometimes | Read the terms: registration, fees, time limits |
| Special coatings | Sometimes | Anti-reflective, antimicrobial, privacy |
| Harder glass | Rarely | Most tempered glass is similar |
| Better impact protection | Unclear | Brand claims are hard to compare |
What cheap glass gets wrong
- Rim-only adhesive, which leaves air gaps and upsets ultrasonic fingerprint sensors.
- Printed borders over sensors on edge-to-edge designs.
- Loose model lists that claim to fit several phones.
- Coatings that wear fast, so smears stop wiping off sooner.
Buying known budget brands (Ailun, JETech, amFilm) avoids most of these for a small premium over unbranded glass.
A simple rule
| Situation | Buy |
|---|---|
| New flagship, first-time fitter | Mid-range with a tray |
| Anti-reflective or privacy needed | Premium or specialist |
| Two-plus-year-old phone | Budget multipack |
| Kids' phones and tablets | Budget multipack |
| You break protectors often | Budget multipack, or a replacement scheme you'll use |
Questions people ask
Is a £30 screen protector better than a £8 one?
It may have a better tray, tighter quality control or a replacement scheme. The glass itself is often similar.
Are replacement guarantees worth it?
Only if you'll register the product and follow the claim process. Check fees and time limits first.
