A lifetime guarantee comes with the cell phone screen protector. However, you have to pay for the shipping at a cost of $7.99 each. I had 2 screens to replace. The packages arrived in thin cardboard envelopes not much thicker than a paper envelope. Both screens were completely shattered. I paid $7.99 each this packaging, seriously?
I contacted the company and they would not refund my money; but, they did agree to send out 2 more with "a bit" more packaging. They arrived undamaged. I give 3 stars for customer service only.
