Next we have a real glass screen protector from a company that's a part of the "made for Samsung" partnership. Meaning they're certified to make accessories for Samsung devices, by Samsung themselves. It is also a glass cover that doesn't have a color-matched front panel. The entire thing is see-through glass.
Tech21 uses BulletGlass, the same type of technology used in bulletproof glass. It should be similar to other glass screen protectors, just very durable. This offers edge-to-edge coverage, scratch resistant and is almost bulletproof.
The company uses an easy bubble-free installation process with a tray to get it aligned perfectly. Then the cover itself is cut to precision so it isn't too big or small. Each protector is made to work with Tech21 cases, or any case for that matter. So it will cover just enough to keep the entire phone safe, but not too big that you'll have that halo we see on some devices.

The company will also have film screen protectors available at a later date.
