Don't use Bearskin on a screen if it's already cracked or broken. Bearskin adds strength to your screen by covering the surface with a powerful coating that depends on the structural integrity of your device's screen.
Under normal circumstances, Bearskin lasts a year. That's how long our Utterly Insane Warranty protects it. If you plan to do the kind of crazy demonstrations we do, like demanding people scratch your phone screen with your keys (don't do this!) it won't last nearly as long.
Bearskin™ is a case alternative, and it's not as good at protecting your phone as some cases. Bearskin is for people who appreciate their phone's design or who find cases to be bothersome, but who still take fairly good care of their phones. It repels dust, bacteria, water, and scratches, but it won't protect completely against direct mechanical damage like some cases. (We have tested Bearskin extensively and found it to add some mechanical protection. We have even found it to be stronger than some cases. But we don't guarantee it against that kind of damage because we aren't sure how to measure the protection it does offer.)
Bearskin definitely won't harm your camera lenses. You should absolutely apply Bearskin to all the lenses on your device. It passes all chromatic aberration tests with flying colors and will deliver amazing protection against dust and other particulates.
Bearskin is optically invisible. It does not give the phone a matte appearance. It preserves the character of the phone's exterior completely. It dries to an extremely thin 'hard shell' that will be imperceptible to you.
We can't recommend Bearskin for drop protection. It does a fantastic job of scratchproofing your phone, but we haven't figured out how to measure how much structural integrity it adds to the case exterior.
In simple terms, the Utterly Insane $100 Protection Plan™ covers your phone for up to $100 in repair costs if you apply Bearskin and your screen breaks during the coverage period. For an exact legal description, please see https://getbearskin.com/guarantee. That means I'm getting up to $100 coverage for $50? Are you people idiots? We're a little scared too, but we really believe in our product.
The Bearskin Utterly Insane $100 Protection Plan works like this. If you purchase Bearskin and your screen breaks during the period of coverage, we'll pay up to $100 of your screen repair. That's at least twice as much as you paid for Bearskin. So what's to stop bad people from buying broken phones, registering them, then demanding the $100? A picture of your phone and its IMEI number, that's what. We can't just do a screenshot because the screenshot is only a digital representation of what's on the display, not a picture of the screen itself.
We hate this too. If you have a better way to help us protect against fraud, let us know by mailing firstname.lastname@example.org. We'd love to hear from you.
