When should I use a bungee?Updated 2 hours ago

Any time you're off smooth, level ground. Sand, grass, gravel and anything that pitches will move a load that would sit still on pavement—as will two or three SmartBins stacked, or a bin riding on top of a cooler. A single SmartBin on smooth, level ground holds itself: its feet seat into the SmartDeck and stay there. That's the one case where you can skip it.
