I have the 15/18 attachment. New and never used. If you are interested send me your phone number. VG

a drop of oil before each use to reduce friction helps

I have this part, and since I cut my hair with it, my once thinning hair grows full and lush again! And I don't have any grey hair any more either. No, nonsense, that's a mistake, I doubt I paid more than 100.- for it back then.

The cutting width is 40mm

Unfortunately no, there are 3, 6, 9, 12, 15 and 18mm.

According to our own research, the model ER1411S503 is a newer version and has different operating times. The model ER1411S503 has an operating time of up to 80 min and the model ER1411S501 has an operating time of up to 50 min :)

Unit can be operated without battery without any problems. Once charged, it can be used several times.

Yes this Hairclipper has a cutting length range from 1mm to 18mm.
