Review on 🧀 3-in-1 Rotary Cheese Grater and Mandoline Vegetable Slicer with Interchangeable Stainless Steel Drum Blades - Easy-to-Clean Rotary Grater Slicer for Vegetables, Fruits, Nuts, and Cheese Shredding by Mary Maybank

The handle will not disengage when you "press it all the way down and hear a click" telling you it's locked. In terms of cleaning, for many years I washed parts with running hot water and without soap I have not died and have been alive for 73 years. old lol. I let the parts dry in a dish rack. This item is very easy to assemble and disassemble. I didn't even look or read the instructions. The suction blocking bottom works very well. You must attach it to a "smooth surface". I use this article without closing it all the time. I bought this product mainly to make hash browns. It does a great job.
