Medicube Age R booster H skin device

Medicube age R booster h, bought it from Medicube website about six months ago, used it consistently once a day for a month then I fell out of the routine, item is in its original box, with its original charging cable and user manual. The machine body is 98% brand new, slight scratch mark on one side as shown in photo. This device is stinging when used in higher level, and I recommend to use it with thicker water based moisturizer, I feel like it doesn’t work well with oil based skin care.
