Laptop is in great shape and works perfectly! It was VERY LIGHTLY USED but we just don't have a need for it any more. The charger cube was used a lot for phones and ipads so it has more of a used look, but other than a couple of dings (see photos) the laptop is like new.
Oh sorry for any confusion--the charger cube is not included, I forgot my daughter wanted to keep it. The laptop seems to charge fine with most USB C charging cords.
