Slow Feeder Metal

The constuction and quality is great. Noticed the change in grind consistancy for the better. Now the flavor of my coffee is better. Thank you.

Great product, with problem

Great product - enjoyed using it both for filter and espresso. Results are especially noticeable for espresso for me. I almost missed the adapter included with the shipment among brown paper, but once I found it, everything fit perfectly. Slow feeder barely fit on top of original Zerno z1 funnel, but fit perfectly with adapter. Great job guys!

Well built feeder. Haven't experienced any stuck bean so far. Battery life is great. I would say, in term quality of espresso, adding a slow feeder to 64mm flat burr grinder could be a cost effective solution than upgrading to a larger flat burr grinder
