Better products available elsewhere [SEP] Used it for shaving head using the cutter first and then to smooth with the shaver.  After the single-use, I opened and cleaned dry. After a couple of days when I tried to shave the facial hair, I felt sharp scratching on my cheeks and neck and I could not proceed with shaving any longer. And I reverted back to my old shaver. I am not sure what went wrong or whether it is because of the substandard blades. But it was quite an unpleasant experience. Returning the product.
