Review on Ultimate Hair Styling Tool: 3-Piece Manual Trimmer Comb - Portable, Multifunctional, Adjustable Hair Clipper for Travel, Haircuts, Split Ends & Face Grooming by Lacey Barbee

The advantage is that the cutting length can be adjusted. Time will tell if he wins. So far my first use has led me to believe that this is an unstable trimmer. More effort required. The price is reasonable for trying it out. The "drop down" razor section takes it one step further. It gave me a great shave. The hair cutting part is still unstable. I never figured out how to get a straight haircut. However, its still low price and versatile uses make it an easy affair to toss in your travel bag. I can just throw it away when I come back.
