i just received my Amazon order for the Eco Pad. I tried regular ground coffee and it doesn't have the strength or quality I was looking for. I'll pick up some finely ground coffee tonight and post my experience. The Eco Pods are pretty nifty. The pod instructions say use the single serve button and you must use the 2 cup tray. I hope this Senseo pod replacement gizmo really works. I'd be grateful for any tips.
