excellent [SEP] i bought mine years ago when this model first came out i noticed the battery was not 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
