At Mobile Reviews Eh!, we do reviews based on actual usage. We do tests and use the products for days and maybe weeks. For this Spigen GLAStR Nano Liquid  Screen Protector Review, we did a couple of scratch and oleophobic tests. We also did a longer in depth review about the liquid screen protector in general with CrystalTech Nano 2.0 and Whoosh Diamond Defense.

Spigen GLAStR Nano Liquid Review

From our understanding, every liquid screen protector is generally the same. Itʼs made from Silicone Dioxide or SiO2. Itʼs liquid glass. Youʼre basically adding a thin layer of glass to your existing glass. The Spigen product is made in America which might be important for some because of tariffs.

Every liquid screen protector we used was installed in the same manner. Clean your screen and then use a wet wipe to slather the liquid screen protector all over the screen of the device that you want to use. For our oleophobic test, we used an iPhone X which had 1/2 of the device stripped down to the glass with a magic eraser and an 5 year old iPad.

We did water droplet tests on both devices prior to adding the liquid screen protector to see how poorly the oleophobic coatings worked. We then installed the screen protector, waited 48 hours for the product to fully cure and tried the water droplet tests again. There wasnʼt much of a difference between the two which was disappointing.

Our fingerprint test also didnʼt fare any better which was disappointing.

One might think that nothing was actually applied to the screen but the screen on the old iPad felt like new. These liquid screen protectors technically smooth over older screens, filling in the gaps where the previous coating has been worn down so having our iPad screen feel new again was a pleasant surprise.

When it comes to scratch resistance, the Spigen GLAStR Nano Liquid screen protector technically does improve the scratch protection of your device The Spigen GLAStR Nano Liquid glass is of 9H hardness which is cool.

Youʼre just basically adding a thin layer of glass to your device which will improve the scratch resistance. However unlike traditional screen protectors, you canʼt remove it after it gets damaged. Your devices will look like your screen is permanently damaged or technically is permanently damaged depending on how you look at it. The normal round of rocks, keys and knives didnʼt leave a mark. The only thing that would scratch the product was sandpaper which was expected.

In our opinion, the Spigen GLAStR Nano Liquid doesnʼt seem to add much in terms of scratch and oleophobic protection. However, it does add a bit of impact protection. That is enough reason that we would put it on a naked screen as well as a screen protector. The sensitivity of the device isnʼt going to be impacted by the product. With that setup, youʼre going to have above average protection for your smartphone.

Also one of the benefits of the liquid screen protectors is that after you use it on one device, you can use it on another. We were able to get four uses out of a liquid screen protector with the last application being used in the impact protection test we did with the CrystalTech Nano 2.0.
