Welcome from MI.
Are you talking about the wood thingy that you use to press seams similar to this one?

Then, Yes, I have one, use it and like it alot.
I use it to press shorter seams, then press with an iron when I'm done piecing the whole block. Just straight seams, though. I seem to stretch diagonals too much.
