It seems to work properly. But when I case opened to adjust output voltage,I found print circuit board of input terminal side is rainbow bowing.I guess the board would break down soon because of tension.And case is deformed shown as pictures.They are defective, I thought. So I asked about these things to the shop. However, the staff answered all things are correct or within their allowance. You should know voltage display of US plug type is not either LCD or blue LED.
