As Beard Trimmer Grundig MC 3140 may go so fine. But if the device is working with the attachment for different hair lengths, do very quickly on limits. The cut hair implant themselves in the tower, so the shears can no longer work and then have to be continually plucked with hands to a large extent in order to continue working. My conclusion: there are much better equipment in order to maintain a short hair on 4mil.
