Fact: I have owned many many men's electric shavers over the years and no matter the cost, they all have a certain life-span. I think the key to longevity for any of these is to be reasonable in its use. Just as you wouldn't use your lawnmower to try to cut a hay field, you shouldn't expect any shaver to handle a heavy growth of facial hair. Shave often, or, if you don't, then first use a non-electric razor, like a disposable one, to eliminate the "heavy timber". Then do the "fine-tuning" with this excellent electric razor for a silky smooth result. After every use clean it thoroughly for best performance and charge regularly.
