This is a junk item. The lower right aluminum frame is warped due to a drop (around the Enter and period keys on the numeric keypad). As a result, the Enter key is also tilted. I tried slightly shaving the Enter key where it interferes, but the area around the depressed printed part has a poor response. It responds normally if you press above the middle. There doesn't seem to be any other aluminum warping. It sits firmly and stably when placed down. In addition, there is a dent on the Return key, and the aluminum next to it is chipped about 1mm. The aluminum edge between F1 and F2 is chipped about 8mm. The aluminum edge around F7 is chipped about 0.5mm. There are also minor scratches and dirt. There are small scratches on the back, but other than the lower right, it's generally in good condition. There is some shine on the keys. I have confirmed the operation of all other keys. They work normally. The Enter key is the only issue. Charging is also not a problem. There is no original box, only the main unit.
