So I've been arguing for a long time between this and more expensive model. I finally chose this because I only had a few pieces to cut out and they are pretty flimsy (Webber kettle hole for a temp connector, sheet metal for a DIY project, etc.). I'm kicking myself now. I received it today and decided to use it on the webber as I was planning to do it tomorrow. We made the necessary preparations and started. I should have stopped when I realized it would take some effort to get the smaller piece to hook and drill the first hole in the grate, but I insisted. After the beginning was finally sunk, the hole saw worked and we continued down the slope. The end result is a sore wrist, an uneven hole, chipped porcelain 1/4 to 1/2 inch outside the perimeter of the hole, and an extra 30 minutes of my life wasted filing the remaining rag and smoothing the hole, but this point. Learn from my mistake and pay an extra $15
