I have had one of these for a few months.  As most everyone agrees, it is very difficult to rotate.  On another seller's website, I read that one person tossed the rather useless base on this composter and built their own using 3 or 4 inch casters mounted on a pressure treated base.  I did this and it is an improvement, but it still requires a lot of effort to get it to tumble.  What I did was raise it about a foot off of the ground with the pressure treated base which will allow me to dump the contents in place and then shovel them into a wheelbarrow. I can't imagine trying to roll this beast around the garden.
