Philips One Blade Head shave

I have to shave my head; mother nature is against me and I have tried a lot of trimmers. But I have always chickened out from wet shaving my head. Always thought I would shred my head to pieces. Since trialling the new One Blade I thought it was a good opportunity to see if it was better than what I already use of if it could cope with a head shave and how close it would be.
