I have the first Olfa I bought 14 years ago (when I started quilting again). I have a few issues, but haven't cleaned it as often as I should - I get a little skipping, but not much. I bought a second to keep upstairs. I have the Brooklyn Revolver rotating mat and a couple of Fiskars that rotate -- the Fiskars are a pain to cut on, love the cutting surface of the Brooklyn but sometimes it rotates too fast for me, though it is my first choice when trimming blocks.
