Oh gosh, I just got one and I love it!!

I have the Fiskars and hate it. The top part does not lay flat so it doesn't ride on the center circle on the bottom portion. (I'm not describing this well) It doesn't rotate, it just slides off.

I have a 12x12 Olfa rotating mat. I put it on my Xmas list a couple years ago. I love it for when I am making flying geese blocks and squaring up blocks, especially. The BOM I am doing this year has bunches of little template pieces...it is nice when I am cutting them out, as well. I know they are pricey but once you have used one, you will be very glad you have it!

I used mine all day, today. Love it. I am working on 12.5 blocks. my mat is 18x18.

Edited to say that mine was a gift. I hesitated to buy it for myself, but I don't know why. It is very useful to me.

I have the Brooklyn Revolver and I like it, but as Maride said it's round which limits the size block you can cut.

I would like to get the large Olfa sometime, but just haven't seen it at the right price yet.

I am going to check them out - you all make it sound so wonderful.

I have the 12x12 square one; got it at Michaels with 50%coupon; it's also sold at Joann's.
It's annoying, it does not turn easily and on my cramped/cluttered cutting table it's always bumping into something.
I have an enormous stationary cutting board (about 36"x24") that I've had for 20+ years and use for strips.
The rotating cutting board that I found and love is an 8" round one...The pieces I cut are rarely larger than 3"x6" which fit.
It turns easily and smoothly. It can be had from Come Quilt with Me, a mailorder vendor in Brooklyn, NYC. Pat Yamin, the owner, also sells very good templates which can be used for hand or machine piecing. Google the name and you'll get to her on-line catalogue.

I have one and used to significantly use it. When I got my Short Cut ruler, I really stopped use the other. I use the Short Cut in one direction and pick it up and use it in the other.

I really appreciate everyone's response. I have a birthday coming in a few weeks. Think I will start dropping some hints about this. If all else fails I will have to look for a coupon and buy it for myself. But, as the old hair coloring commercial said "I'm worth it!" Dixie in AL

Have the 12 inch Fiscars, and love it. Great when Paper Piecing
