I have one. I got it for my Viking Topaz and love it. I got the insert for just sewing with the machine and the solid insert to set the machine on top for the embroidery sewing. It comes assembled so you don't have to do anything but pull the legs out. There is also a cover so when you do take it out it is protected or put it away (like that is going to happen). I love it. It came so fast - I actually had it in 2 days! (That could be because I live in California and they are in Nor. Cal.) That was totally incredible to me.
