Portable Roll-Up Piano works BUT has battery terminal corrosion

This 49 key piano portable piano role is more of a novelty than a serious musical instrument. The batteries had corroded inside so there is corrosion in the battery terminals. You need to have the batteries in just right in order for it to work. It still works but sometimes you need to rotate the batteries in the terminals. Buyer beware. Sound is not great a little bit distorted. Questions? Leave a comment below!
