This product works well, apart from starting the procedure. When pouring the juice/fat mixture into the separator, the fat rises to the top of the main vessel and also the spout. Tilting to pour off the fat in the spout isn't entirely effective, since juices come away as well. Inserting a plug of kitchen roll into the spout to soak up the fat is a somewhat messy option. Better to have a means of closing the hole between vessel and spout, so that the poured mixture could settle, then opening to pour the juices. A simple spatula with a soft dished end (low-cost) should do it.
