Review title is excellent [SEP] 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.
