Quick look at the CrystalTech Nano liquid screen protector demo
In the past, if you wanted to add some protection to your precious smartphone or tablet, you had to consider a glass or plastic screen protector. These were very difficult to install, often introduced grit and bubbles and were inconvenient. CrystalTech's Nano liquid screen protector is liquid applied to smartphones.
CrystalTech Nano offers invisible protection, reinforcing your smartphones or tablet’s screen to 9H (sapphire equivalent) hardness for ultimate scratch resistance and is easy to apply while leaving no annoying bubbles. But it gets better.
