Who is 7Tech, and why should I purchase this? You have two separate questions here. Separate them
7Tech is one of the leading manufacturers of the Nano Liquid Screen Protector. 7Tech was founded back in 2015 and has been a leading mobile device accessory brand since then.
We are so sure that our products are in a league of their own, we are offering a no-questions-asked refund or replacement if you are not happy with the products' performance.
What is 7Tech Nano liquid?
Years of work combining science, engineering, and the latest technology "Nano," we take advantage of the nanoscale's enhanced abilities: higher strength, lighter weight, and increased control during installation. Unlike other brands you see, 7Tech has developed its unique formula, which is better and more durable than other generic formulas. We combine those attributes with the latest engineering to create the best universal screen protector on the market. Better than glass and plastic.
How does it work?
The exact formula is a kept secret, but we can tell you that SiO2 is the main ingredient. It is about 500 times thinner than a human hair, and after the application, it forms an invisible protective layer bonding to the glass surface. The SiO2 can fill small pores on the actual glass, thus creating an invisible protective coating. There are no bubbles and no dust or moisture getting between the glass and the bonded 7Tech product. It's a "One Size Fits All product" 100% compatible with any smartphone, including those with curved/concave screens and small to large-sized surfaces including tablets, watches, laptops, basically any glass surface.
Is the video on your listing with the knife, scissors, and hammer real?
Yes, the video demo is 100% authentic but not made of steel. It would be best if you still were careful because accidents do happen.
Can my screen break with your 7Tech original liquid screen protector on it?
The simple answer is -Yes, there is no product in the world( bold statement ) that can completely protect from scratches or breakage- it there was, we would all be using it. They are all designed to add more layers of protection to the screen, but none can completely prevent breakage, nor will it make existing scratches disappear.
Can my screen still scratch with liquid glass?
Yes, it's still possible that your screen can scratch. Our product and all other products for that matter are "scratch-resistant," but not "scratch-proof." What is the difference? Scratch resistance will make your screen less likely to scratch during everyday use. Full scratch-proof does exist for consumer devices. If you see a product making these claims, beware.
Is it harmful to my device?
No. The 7Tech original liquid screen protector is entirely safe to use on any smartphone or any other device with a glass surface. All products are certified, and lab tested.
I have face recognition and or fingerprint reader on my device. Will this product cause any issues?
7Techs original liquid screen protector has been tested and is 100% compatible with all phones and tablets using face recognition and fingerprint readers.
As far as we know, this is the only product on the market that can allow security protection options.
Tempered glass, flexible films, and silicon screen protectors may cause interference and the need to re-enter the face and fingerprint readers.
Can I remove the coating?
We get this question a lot. It is not removed since it bonds directly to the screen. There is no need to remove it or put plastic or glass over it.
7Tech original liquid screen protector protects without being noticed. There is no added bulk, no bubbles, and the product is universal. You don't need to purchase individual screen protectors for each device you own. Remember "One Size Fit's All "
Can I use it all over the screen? Camera lens? Entire phone?
7Tech liquid glass is designed to bond directly with the glass surface of your smartphone or other devices. You will not reach the same results if you apply it to other materials; we do not recommend you try.
Our recommendation is to apply this to the original phone screen and on the front and back camera lens.
My phone fell, and the screen broke; Do you recommend using the 7Tech liquid glass?
There are two answers:
1- To be perfectly clear- this will not fix the screen, but it may help prevent the screen from further cracking.
2- If you try to apply the 7Tech liquid screen protector onto a cracked/broken screen, it won't help. The best solution and advice is to replace your screen first and then apply the 7Tech liquid glass screen protector over the new.
