This product is overall great, I am sure the higher mm versions may function a bit better than the 51 mm version. This would be due to the max depth that the needles distribute at – The 51mm baskets are smaller in diameter but deeper in depth than say the 54, 58 mm baskets which are higher in diameter but shallower. The needles don't reach the grinds at the bottom of the basket but rather just the ones in the first half or so at the top even when the product is adjusted for max hight.
