Don't expect their warranty to actually fix your phone. I went through 8 months and they charged me $300 for a broken screen repair (ROG Phone) and when it was finally returned to me, the NFC and RGB are broken and the screen has a dark orange splotch in the upper right corner.
And then the ROG 2 not even 2 years in was dropped from AT&T's network because ASUS didn't include the bands (: how stellar.
I'd go on about my other ASUS horror stories, but I'll keep it relevant with my phones. I'd... Avoid them. It's too bad cause I really wanted them to be a viable alternative but they haven't been making good moves recently and these customer service and warranty stories are years in the making
