it is sooo expensive tho but I can't seem to trust 2nd hand Iphones they might have issues later on... have a long history of problematic 2nd hand Iphones from the Iphone 5s, XS, 11 pro and this Iphone 8+ which is glitchy af.
got a brand new Iphone 8 then coz it is small and that was crappp hahaha. I did nothing but charge it twice a day.
