Yesterday I had water damaged on my iPhone6. The screen turned off in seconds. They gave me a receipt and told me if they can fix it it will cost me $49.99 which for me is cheap compare to buying a new phone.
They said if they cannot fix it, I will pay $0.
Today they called the phone is ready, and I don't have to pay for anything since they did not replace any parts.
Honest service, I am a customer for life.
