Review on Under Cabinet Sliding Coffee Tray Mat - Kitchen Caddy for Coffee Maker, Toaster, Countertop Appliance Storage - Smooth Rolling Base Shelf with Wheels (2 Pack) by Angela Tarpley

This is a replacement batch I had to get from them as both of the first batch were broken. As long as they work well. I think the lower part of the caddy is not needed. They don't stick to each other. The top just sits on top of the bottom and the top is the one with the wheels. I think it would have worked if it was just the tip, but I've used both since they were there. Works great for my coffee maker. However, my stand mixer is too big to roll in and out, but that makes it a little easier to get out from under cabinets. So far I am satisfied with the purchase.
