Trimits Rotating Cutting Mat

I bought one of these from another retailer, and I have been so disappointed with it, the mat is basils two parts. One is the cutting board and the other board with a mounting disc it for the cutting mat to sit on. Maybe mine is defective I don’t know but the mounting disc is a plastic thing which loose in the mount board and if you rotate it 9 times of of ten it will come away and not rotate. The plastic thing drops out and the whole thing is useless as a rotating cutting mat, I bought it while away and since then two lots of lockdowns and have prevented me from returning it. I will just use the mat as a stand alone. So save your pennies and buy something else.
