Good days, My friend.
This is pan from YYTOUCH company. We focus on OEM mobile phone parts.
We offer 1 year of warranty, and will 100% test before shipping. I know your main concern is about return, so we suggest ESR quality, it's more bright just as we showed you in the booth.
Sincerely welcome to discuss more details.
