No questions about it; The Wahl Balding Clippers are what you need and are all you'll need for a very long time. I've had my set for upward of five years and apart from a few drops of oil, that's it as to maintenance. Keep this in mind, if your hair, or what is left of your hair is dark, nothing, not even the closest blade shave will conceal the "shadow". Understand that going in and you won't feel cheated when, after you've used the Wahls or a straight razor that the "look" you want isn't there. In terms of finance, over five years I've saved far more than the purchase price and that assumed I'd had my hair buzzed at the barber shop-locally, the cost for that is (USD) $7.00. Additionally I found that I could whizz them over my face when I hadn't bothered to shave for several days which produced very short stubble, as if I hadn't shaved in several hours (as opposed to several days.) Don't even hesitate; Buy The Wahs.
A very satisfied user. (Check the reviews for these at Amazon.com)
