Crystal Armor Fusso Cell Phone Fingerprint Oleophobic Coating Kit 3ml from Japan

This stuff works great and is even cheaper than comparable products despite being a Japanese product. I suspect the poor reviews are from people who didn't take their time to properly prepare and apply the coating. Your screen has to be initially cleaned thoroughly with isopropyl alcohol to remove any trace of oil and other contaminants. The product dries very quickly, and you must apply it in sections using a non-absorbant plastic as others recommend. I work in 2-3 drop sections, about 6 sections total for my fairly large S23 Ultra screen. I let it cure for 8-12 hours and repeated this process for a few days to build up multiple layers, only cleaning with water and a microfiber cloth after the initial layer.The reviews claiming issues with the product are absurd to read. If you receive and empty bottle, that is not the fault of the product, it is likely the fault of Amazon who stored it at some point where it got crushed and spilled. You can easily receive a refund for this. No, finger prints will not magically disappear from using this product. Your screen will feel much smoother, not hold on to as much oils, and be easier to clean. I saw someone saying they wanted to coat their entire MacBook in the stuff, keyboard and all????? Who thinks of that??? Someone also complained about whenever they touch their phone, dust coats the screen? I've never heard of anyone having an issue like that. Either that person is constantly coated in dust, or they use their phone frequently in some kind of woodworking shop with lots of fine dust.Please be realistic, this isn't going to make your phone permanently clean. It's just an oleophobic coating and it does just that.

Works very well so far, I have a third party replacement screen on my iPad that collects fingerprints like there's no tomorrow. This product made it feel like a new screen. The directions are in Japanese, and the YouTube videos showing how to apply it are incorrect. Here are the translated instructions straight from the box-How to use Wipe off the dirt on the tempered glass surface well with the included cleaning cloth before use. ② Reinforce Fusso SmartPhone Apply 10 to 15 drops to the glass surface of the smartphone and quickly spread it thinly with tissue or vinyl. (As the liquid absorbs moisture, please extend it with a small amount of tissue or a piece of plastic bag that does not absorb moisture etc.) ③ Repeat the work (2) 2 or 3 times as it will dry immediately . It takes 8 to 12 hours for fluorine to bond with the glass at the molecular level. It is desirable to leave it for about 12 hours from the coating time. * In the winter, as the temperature is low, please take longer leave time.In other words, use a piece of plastic to spread it, NOT A CLOTH. Let it set overnight and wipe off in the morning. The longer you let it set, the better. Follow this and you'll be rewarded with a smooth as silk screen that repels fingerprints. Thank you for reading.

This product does not work at all. As someone who's detailed many cars and applied crystalizing ceramic coatings (Adams, Gtechniq) I know how important prep and application is.Phone was thoroughly cleaned prior to both applications leaving behind no residue or oils. Applied a rubber glove spread the product in cross hatching patterns multiple times before leaving it to cure for 12 hours while using my backup phone. It wiped away with no issues but immediately accumulated oils. Wiping the oils away with a quality microfiber and slight mist of water made no discernable difference.Thinking it was user error, I did this again the following day. Cleaned, applied in cross hatch side to side, up to down, then one last clean swipe of product from left to right only for even coverage. Let it sit for TWENTY FOUR HOURS. Still does not reduce smudges and wiping away is no easier than it was before.This product is snake oil. I would not recommend. It was cheap at least. Shocked because I believe this same company has a very reputable car wax that I've seen in person.

Wow!!! This stuff works wonders! I purchased it 6 months ago and finally used. It made a huge difference on my screen. No longer a fingerprint magnet. Only wish it was still available.

I did a lot of reading and video watching before purchasing this to make sure i would know how to apply this once I bought it. It is very easy to apply. I used the plastic wrapper from the cloth to spread this evenly. you have to work quickly as it evaporates fast. it appears smudgy at first but once dry, you wipe it lightly to a shine with the cloth. I then let my phone sit all night. I used the phone the next morning and found it slippery to the touch but after an hour or so, it was evident the missing spot was still there. I followed the procedure exactly the 2nd night and woke to the same results. .. and again the 3rd night. I was mindful to apply a decent amount each time. Personally ? I think this works well as a lubricant but as a "layer building" replacement to the original oleophobic coating, I am not sold on it. I have a little over 1/2 the bottle remaining. I will try it again and again. If I find results that improve on this review, I will update this review.
