I have one. I bought it while I was waiting three years for my Genesis trimer. I actually use my Rotatrim more than my Genesis. The cutting grid took me a while to get used to and for a little while I was convinced it was crooked, but it was just me
I like the weight of the trimmer, it's solid enough that's it never shifted on me while cutting, it will cut off a tiny sliver of paper. I'm very happy with it.
