Three very short videos of the Wonder Barrow in operation are shown in a Youtube playlist. You will see how quickly you can load and unload 40 cubic feet of leaves. In the 2nd video, you will see the benefit of the ejector rope which is used to empty the load completely.
The 3rd video of the playlist shows loading of wet leaves from the side. A fork is used for most of the loading since it is too heavy for a rake. It takes my full weight to set it upright, which illustrates a structural integrity beyond the normal need.
