Really doesn't make sense with this product. I would contact Digitec customer service to have this adjusted as soon as possible: digitec@digitec.ch

You can choose which scope of delivery, 6 or 9 attachments. With the one with 6 attachments you have a maximum of 5mm. A mistake that I only saw on delivery. I don't know what the maximum length is for the one with 9 attachments. I have also not yet found where you can reorder just the attachments.

Unfortunately, we do not have replacement blades for this razor in our range.

Yes, an adjustable attachment is included 3,4,5,6,7

Yes, as stated, the device is battery operated, i.e. it has a rechargeable battery that must be charged. 60 min is the battery life

If you only need one item, you have the option of using the linked supplier. We can currently only obtain the set of 4 from the supplier and offer them accordingly.
