I bought this as a replacement of my 8 year old Norelco. So far it's been more than three weeks and it is still charged and shaving fine. I especially like the hard travel case. You have to remember to empty it after each shave or the red light comes on. much smaller space than the old one. It sans to always rinse with hot water, but I'm only doing that every few days since I don't feel like running water till hot gets to the bathroom in the morning after swimming.There are huge price variances for this. Amazon showed them all and I got it at about half price.
