I purchased an older relative of this shaver 3 years ago, impressed with the whole faster motor thing. It performed extremely well, as I used it almost exclusively wet in the shower.About a year ago, the older model started conking out and after some research, I decided to once again go for the panasonic linear 13000 engine.This time, it took only 4 months for a breakdown to occur. The shaver went completely dead one day. After negotiating Panasonic's immature site for service support, I was directed to send it off to San Francisco for repair under warranty. Two weeks later, when checking for status, I was told I should have sent to to Connecticut. Three weeks later, they needed to order parts. Expected delivery in 5 weeks.Bottom line: Excellent shaver when it works. But reliability is a big concern as Panasonic contines to struggle with the battery power and the electronics inside. Service is well below market standards for such a large company.
