I bought this when it was first released, but I've been storing it at home since I bought a 5-blade shaver. Two years ago, when I moved for a single-person assignment, I replaced the outer and inner blades with new ones and used it only about two days a month when I returned home. Now I'm selling it because I've bought a new one. Charging and operation have been confirmed to be working without any problems.
