Yes, I continue to be pleased with my design -- very repeatable, easy to use, etc. -- but keep in mind it is really only suited to round pots.
Incidentally, I'm intrigued that the professionals make the horizontal cut first -- when I've tried it that way, I don't get as good results; it seems as though the curds tends to knit back together more (due to the weight, I guess), whereas if I make the vertical cuts first, then the curds a a little more free to separate.
