I'm familiar with the cutter you are talking about. They do work very well (some might say they are idiotproof ) BUT it all comes down to the vitola of cigar and the smokers preference so they're not always suitable.

I'd personally rather not cut a cigar down several times incase it put too much stress on the cap. I much prefer getting it over in one clean cut

I used to stock those cutters and only really sold them to people starting out that weren't comfortable with judging the cut themselves or people with arthritis, etc
