Hello, I cut my husband’s and 4 sons’ hair. If you have more than one person’s hair to cut, I strongly rec getting professional grade clippers at a beauty supply store. I was using Wahl clippers that my parents bought 35 years ago until I couldn’t get the blades sharpened any longer. We would burn out the motor in drugstore models in a matter of months. I went to Sally’s and spent about $50 which I made up in 2 months.
If you have young children, check out the Peanut clippers from Wahl. They make it much easier to edge around little ears and necks but it doesn’t really take that much longer to do my husband’s hair than a full size pair. After 2.5 years, I replaced the blades and bought 1 more set of guards.
