There is a problem. I bought 3 times so far, but I failed 2 times. The screen is blinking.
Good product, Satisfied it. but not good enough in communication. Requested to change product type just after purchase with chatting but they ignored it.
They send another product for free. Very satisfied it. 변경 요청한 제품을 추가로 보내주었습니다. 굿!
