I have read a lot of reviews for this product, and I am not convinced the people posting reviews have all used these clippers. I have been cutting hair for 20 years, and this is the first set of balding clippers I have ever purchased (never really had a need). First and foremost,these clippers are very sharp, and if you are not careful, you will put deep gashes in your skin! If you have bumps or moles on your scalp, these clippers will surely slice right through them. That being the case, of course, these clippers also cut hair very well, as they should. Wahl makes excellent, long lasting clippers. As I said, I have been cutting hair for 20 years and these clippers really aren't for amateurs or do-it-yourself head shaving. If you're using them to cut your hair, or the hair of someone else, take your time, keep the top, flat portion of the blades flush with the person's scalp (to minimize cuts), and be very careful around the ears. Second, for men that wear do-it-youself, clean-shaved heads, these clippers are not a good alternative to shaving your head with razors. Try an electric razor (like Norelco) instead, and then clean up the straggler hairs with a razor. Otherwise, as I said, be very careful!
