This Review Title is excellent and the content is: I bought mine years ago when this model first came out. I noticed the battery wasn't holding a charge anymore so I bought a replacement set for less than ten dollars and did the simple repair myself as per instructions from the battery vendors website. I am due for a set of replacement cutter heads and it will be good as new. The motor runs a well as it did on the first day and that was about ten years ago. When this one finally kicks the bucket and is beyond repair I will not hesitate in buying another Norelco. It is built to last with the normal maintenance of cleaning and lubrication and if you are a bit handy it will last far longer. This model has an adjustment for closeness of cut for those with sensitive skin and a basic flip out trimmer on the back. The head assembly flips open and is also easily removable for cleaning as are each of the cutter heads for a more comprehensive cleaning job. As per the instructions always keep the individual cutters and foil heads paired when cleaning and reassembling as they wear together..There are other information for this review, one is This reviewer did not purchase it and the other is 1 people think this review is helpful.
