Pretty good, actually. It gets a bit wobbly with the "portafilter wiggle" but otherwise it's surprisingly solid. The shelves provide enough cross-bracing and the mass of equipment holds everyone firmly in place. Although it isn't evident in the pics, I put the floor protectors on the cart's adjustable feet; they're plastic and have a hexagonal indent to fit perfectly.
I've only had my setup for not quite three months, and I'm not sure how much longer I'll be using it, so don't expect much follow-up. I'm probably moving pretty soon-- my better half is looking into culinary school at CIA in St. Helena, and I'm not sure if I'll be able to haul the whole kit out from here in the midwest.
I absolutely dread having to put this machine in storage. Oh well.
