Not too big not too small. Works perfectly for me. My keurig sits on top of it and it doesn't take a lot of space.
Fit's perfect underneath the Keurig. I thought it was going to be a luxury having this (but I guess so is having a Keurig), but it's almost essential. I was tired of storing the boxes full of K-Cups, plus it creates a nice clean look. Also why pay 2-2.5X more for the Keurig branded one? It's simple yet, it does what it's suppose to do. Would highly recommend and would even buy it again.
After we picked it up at the store we immediately loved it. It does not occupy space and it has space for 24 Keurig cups. What I love about it is that it slides easily and it does not get stuck.
