tompoland drdre89 I tried a couple of the OCD spinning things but it seemed to me that they only move grinds around at the top of the puck. Any clumps remain intact at the bottom. So I switched to a puck rake and that gives more consistent results, provided I pay careful attention when I rake. PS I have two of them for different sized baskets I.e. for a 54mm and 49mm baskets.
