Review on ☕️ De'Longhi Stainless Steel Knock Box: Easy & Mess-Free Disposal of Coffee & Espresso Grounds, Removable Bar, Non-Slip Base, Dishwasher Safe - 4-inch Diameter by Mike Shah

It's a handy size but the oversized handlebar grips are unnecessarily large, although would be nice if I had arthritis. The biggest complaint is that its base measures about 4 1/4 inches, with a rubber grommet at the bottom that's only 2 1/2 inches in diameter and about an eighth of an inch thick. That way it will rock back and forth on the pillow when you hit the ground if you're not holding it, which isn't that hard. A major design flaw, however it would have been so easy to put an o-ring around the edge of the floor and make it sturdy. I could get some foam and do it. That looks great. This is a good heavy gauge stainless steel that will be polished nicely. It disassembles for easy cleaning. The base stays in the bin whether it's a clean washer or a little sloppy. It would be a 5* product if it was stable on the base.
