Bad service, they replaced the cracker screen of my iPhone 6S back on May 2016 and after about 3 months the screen literally glued off the iPhone, called them and they told me that their warranty is limited to 30 days only and I have to pay agian for a new screen!!! I tried to explain to them that this is workmanship issue and they should at least re-glue the screen back to the iPhone, they kept saying the warranty is limited till 30 days!!
Terrible company and bad service.
