Although it wasn't used very often, the battery has deteriorated after several years of use, so it's difficult to use it for extended periods on its own. (While not precisely measured, it lasts about 30 minutes even when fully charged.) It can be used without any problems while connected to the charger. Since it was used by a child, I've cleaned it, but there are some pencil marks that couldn't be removed (see photo 9). This is a used item, so please refrain from purchasing if you are looking for perfection or are overly concerned about details. There are no smokers in my family, and we do not have any pets. No claims or returns accepted.
