For bold heads, it might or might not work as expected
The Electric Shavers for Men 5 in 1 Rechargeable Electric Razor for Bold Men Wet and Dry Waterproof Grooming Kit with Beard Trimmer, Nose Hair Clipper and Face Cleaning Brush can work with multiple passes over the same spot, but doing this can cause some irritation over time. I purchased this shaver to keep my head bold and razor close; since I have to go over  my head so many times it gets irritated from trying to get the little stubble i do have on my head, it also leaves bumps at the base of my neck and head. I don't know how long the rotary blades are going to last because they must be dull if I have to go over so many times to get the results I'm trying to achieve. One thing I do like about this razor is not getting any cuts in my head like I do sometimes with a regular razor.
