Great product, but the sizing missed the mark. There is a big gap in the size of the taper, so the larger one is a bit big, and the smaller one is a bit too small. I need the in-between "Goldie Locks" size, so I still had to tape up a good arbor to fit. The taper is a bit steep, so it is lacking support inside the blank- that creates a lot of wobble. The products are built well, so I will give it a 4, not a 3. Design is 3-star, quality is 5-star.
