I tend to be a creature of habit and don't stray far from what I am used to. I have looked at them but haven't tried one yet. I might have to get one and try it.
I used to do everything by hand and was very nervous of having to do all on the machine when I started selling 12 years ago. I decided to buy a rotary cutter and wasn't sure I wanted to use one as I felt by hand was more accurate. But I tried it and after a while I wouldn't do it any other way. So it would probably be the same with this smaller one too. I might like it more than I think. I dont' like the cutters that are the kind you press the handle down to engage the blade. I started with a Fiskars and I can't stand any thing else. I tried my friend's cutter the kind I described above and I wouldn't want one.
I think those are an Olfa brand maybe? I'll stay with my Fiskars!
