I started buzz cutting my own hair with clippers a couple of years ago. I tried Oster 76, Wahl 5 Star Senior with cord and finally settled on the 5 Star Senior cordless clippers. The others were great too but once I tried the cordless version there was no going back to a cord. I believe the 5 Star Cordless still comes with three premium guards with metal clips, the 1/2 (1.5mm), 1 (3mm), and the 11/2 (4.5mm). They are quality clippers and feel very solid in the hand. If you watch a few YouTube videos about them you will find them overwhelmingly highly recommended.
