Best robot cart ever hands down once you take off the side gates. While it doesn't have storage (a few mods will give you a second shelf) it is great for easily maneuvering around a venue and over uneven ground. When my old team went to a regional a few years back we rolled in with one similar to this and got such positive feedback from a few teams later that day a few were getting taken out of boxes fresh from Home Depot.
