Thanks to the useful design of the Philips Series 5000 HC5630/15, your trimmed hairs don't get stuck in the comb. This means you can effortlessly trim your entire head without interruptions. Besides, you're done trimming even faster thanks to the double-sided blades of the hair clippers. With the 2 adjustable comb attachments, you can trim your hair to a length between 3 to 28mm. The beard comb allows you to cut up to 2mm. Do you want an almost bald result? You can trim up to 0.5mm without comb attachment. For the most coarse hair, you can use the turbo mode. You can rinse the hair clippers under the faucet after use. After one hour of charging, the battery lasts about 90 minutes. You can also use the hair clippers corded.
