There is an electric shaver called “Philips Norelco OneBlade Face + Body Hybrid Electric Trimmer and Shaver”. This seems to work similar to a conventional foil shaver. However it seems like it cuts pretty close to the skin. Can you advise if this is permitted or forbidden?
It seems that it isn’t worse than any triple head shaver. In practice it does not cut closer than those. Many Poskim permit it.
All the Best
