My 5s died while updating. Sent it back on warranty- was told it was a mother board issue so elected to take the replacement phone option. New phone was sent even before I paid the $25 deductible. Replacement phone is in perfect condition. The only reason I gave this review 4 stars is because I had to follow up with them re receipt of my my old phone, status of repair etc. They could be a little more proactive there. Otherwise great company, I will buy my next phone from them
