I have the fiskars rotating one, it actually works fine for me...I do wish the rotating ones were even bigger than the 17" one, like my regular mats, I have 2 of the 24x36 ones, so am kinda spoiled to them...but when I am heading to my quilt guild, the fiskars works fine...and I have had no problems with it staying on the base when rotating it...
Good luck,
Kif
