The product is well designed and rugged. It certainly speeds up the process of recycling. Interesting that some components appear to be 3D printed. If the blade was 2-3mm (1/16-3/32 in) farther away from the pod's lip, it would cut the paper filter as well and the cup on Costco pods.
This device has worked much better than previous cutters I have tried. With this unit, I can even remove the foil lid on the K pod to recycle and use the coffee grounds for my compost. Then I use the cutter to remove the ring any filter left remaining. And I really love the fact the blades are replaceable, instead of replacing the entire unit as with other cutters. Definitely would recommend this product!!
I have never used any other k kup recycling tool but no reason to now this thing works great very simple and fast I used to recycle them by tearing them apart with my hands never again there is no short comings to this tool.
This cutter is easy to use, I find it a bit large but strong well built, most the kcups separate easily from top and plastic body however there are brands that the cutter does not grab the filter so it can be a mess. I have found the cutter works best on walmart brands. Still it is good to do what I can to recycle where I can.
