The MSI SP004 9H Screen Protector is a tempered glass screen protector rated at 9H surface hardness with 99% light transmittance. This article works through what the published specs actually tell you, and what to check before buying a protector that lists no compatible devices.
Overview
The MSI SP004 9H Screen Protector is a general-purpose tempered glass film for protecting LCD screens from scratches and minor impacts. The published specifications amount to five data points: 9H hardness, 99% transmittance, model number SP004, package dimensions of 8.79 x 7.19 x 5.89 cm, and a package weight of 77.11 g.
No device compatibility list is provided.
The short verdict: this product suits buyers who can measure their own screen and confirm the panel is flat. Unlike model-specific protectors, where the part number tells you exactly what fits, the sizing decision here sits entirely with you.
If the dimensions do line up, the core features work as advertised for the price class.
It helps to know what the numbers mean. 9H is a pencil-hardness grade, indicating resistance to scuffs from keys and coins.
Quartz grit in sand is harder still, so pocket sand can leave fine lines even on 9H glass. The 99% transmittance figure means the glass barely changes brightness or color, which also means it offers no anti-glare benefit.
Compatibility Guide
The available data states plainly that compatible devices are not specified, that the product is designed for flat displays, and that you should verify screen size and shape before purchase. There is no socket or interface standard involved here, so compatibility means exactly one thing: physical dimensions and edge geometry.
The listed 8.79 x 7.19 x 5.89 cm figure is the package footprint, not the glass itself.
Padding and the retail box are included, so the glass inside is smaller. A flat sheet fitting that box is plausibly phone-sized rather than tablet- or laptop-sized, but that is inference, not fact.
Confirm it against the listing images and description.
| Check | Where to look | What goes wrong if it does not match |
|---|---|---|
| Screen width and height | Measure the active area with a ruler | Glass overhangs, or leaves a visible margin |
| Panel shape | View from the side: flat or curved | Curved edges lift and show rainbow haze |
| Edge finish | Presence of 2.5D rounded edges | Corners sit proud and chip easily |
| Camera and sensor cutouts | Front camera, proximity sensor | Misaligned holes affect calls and auto-brightness |
| Case overlap | The inner lip of your case | The case pushes the glass and peels an edge |
| Fingerprint sensor | In-display or not | Optical and ultrasonic readers can lose accuracy |
The last two are the most commonly overlooked. On phones with in-display fingerprint sensors, glass thickness and refraction can reduce read accuracy, and a generic protector makes no promises here.
With a case, the classic failure is the case lip riding onto the glass edge and lifting it over time. Nothing in the published data confirms a case-friendly cut, so if you use a case, the practical rule is to leave 2-3 mm of clearance from the case's inner edge.
Product Info
| Item | Value |
|---|---|
| Hardness | 9H |
| Transparency | 99% |
| Model Number | SP004 |
| Package Dimensions | 8.79 x 7.19 x 5.89 cm |
| Package Weight | 77.11 g |
The 77.11 g package weight covers the box and any bundled items such as a cleaning cloth and dust-removal stickers, not just the glass.
A single 0.3 mm phone-sized tempered sheet weighs only a few grams, so most of that figure is packaging.
The exact bundle contents are not published, so check the listing for whether a cloth or alignment frame is included.
As captured in July 2026, the listing showed 4.7 out of 5 stars across 2,464 ratings, equivalent to a 94% positive rate.
A four-digit rating count suggests real volume rather than a handful of lucky buyers. That said, as noted below, the source listing's identifiers do not fully agree with each other, so those ratings may not attach to this exact model.
Treat them as a soft signal.
On price: the captured data contains a mismatch in the listing identifier, so quoting a figure here risks publishing a wrong number. This article therefore omits the price.
Tempered glass is a category where sale pricing and pack quantity move the figure a lot, so check the current price and whether you are buying one sheet or a multi-pack directly on the product page.
Installing Without Mistakes
Most complaints about tempered glass come from installation, not the product. Order of operations matters more than technique.
- Work in a room where airborne dust has settled, such as a bathroom after a shower.
- Wipe with an alcohol pad first, dry-buff second, then lift remaining particles with a dust sticker. Reversing this smears the oil film.
- Dry-fit and mark your alignment before peeling the release liner. Auto-adhesive glass is hard to reposition once it touches down.
- Set it down at one central point and let it self-spread. Pressing it flat locks bubble outlines in place.
- Push any edge bubbles out with a fingertip, not a card. A card concentrates force and chips corners.
One trapped dust particle creates a permanent ring of air around it. Do not press harder; lift the glass with tape, remove the particle from the adhesive side, and reapply.
How It Differs From Alternatives
Screen films diverge sharply by purpose, and this one takes the most basic route: keep image quality, stop scratches.
- Privacy filters deliberately narrow the viewing angle so the screen dims off-axis, at the cost of transmittance. Better for offices and trains.
- Anti-glare films micro-texture the surface to kill reflections, useful outdoors, but small text softens slightly.
- Device-specific glass has cutouts and alignment frames matched to one model, which all but eliminates placement errors.
This product is none of those three. It optimizes for clarity and leaves the fitting to you.
Best Use Cases
- Users who refuse to compromise screen color or brightness. 99% transmittance is in the range where you stop noticing the glass is there.
- Users bothered by fingerprints. The anti-fingerprint coating cuts how often you need to wipe, which matters most for gaming and heavy typing.
- Owners of secondary or older devices who want basic scratch defense cheaply, especially for models where dedicated protectors are no longer sold.
- Buyers willing to measure the display and verify its shape themselves. That willingness is the prerequisite here.
Things to Consider
First, the listing metadata does not fully agree with itself: the identifier (ASIN) recorded for the source page differs from the one shown in the listing details. Generic accessory pages frequently carry mis-registered attributes, or pool reviews and pricing from products that previously occupied the same page.
When you open the listing, do not trust the model string alone. Verify the images, title, pack quantity and stated dimensions against what you actually want.
Second, the missing compatibility list is this product's biggest weakness. Returns are not guaranteed, and buying by eye tends to end in a two-millimeter mismatch.
Panels with gently rounded 2.5D edges are especially prone to lifted corners with flat glass.
Third, understand the limits of "9H." It describes scratch resistance, not drop resistance.
Hard glass is designed to crack and be sacrificed on impact, which is normal behavior rather than a defect. Shatter-proof treatment reduces flying fragments but does not prevent breakage.
If drop protection is your actual goal, spend on a case with reinforced corners instead.
Fourth, there is no anti-glare benefit. Achieving 99% transmittance requires a clear surface, which reflects.
Buying this to improve outdoor readability will disappoint.
Finally, generic products vary by batch. Corner chamfering and adhesive quality can differ, so if a multi-pack is offered, having a spare for a second attempt is worth more than the small savings on a single sheet.
FAQ
Q: Does it work on curved displays? A: The published data says flat displays only.
On curved or 2.5D edges the perimeter lifts and can look white or iridescent.
Curved phones need a model-specific full-adhesive protector.
Q: How strong is 9H really? A: It means 9H on the pencil hardness scale, enough to shrug off keys and coins.
Quartz in sand is harder, so pocket grit can still leave lines. It says nothing about impact resistance.
Q: With no compatibility list, how do I choose? A: Measure the active display area with a ruler and compare it to any glass dimensions on the listing.
If none are given, the 8.79 x 7.19 x 5.89 cm package size is your only upper-bound hint, and it is the box, not the glass.
Q: I trapped bubbles. Now what?
A: Small edge bubbles right after application usually push out with a fingertip. A bubble that stays put is a dust particle; lift the glass with tape, clear the adhesive side, and reapply.
Q: Can I use it with an in-display fingerprint sensor or a case? A: Neither is confirmed in the published data.
In-display readers can lose accuracy through added glass thickness, and case lips tend to catch the glass edge. If you need both, a model-specific protector that states compatibility is the safer buy.
