The other person must have a bad set of clippers. I have been using these blades for over a year and they stay cooler longer and clip like a dream. But all blades clip well if you use the right clippers. I will continue to use these blades for the next years of clipping love them the best.
these are the worst blades we have ever used. left streaks or just wouldn't cut through the hair. the coating chipped off after 1 use. would not reccommend!!
