You can easily set the shaving length of the Philips Series 3000 BT3239/15. Choose from 20 length settings between 0.5 and 10mm. You can set these via the dial on the trimmer. That way, you can always trim your beard to the right length. The blades are self-sharpening, which means you don't need maintenance oil or replacement blades.
