What a nice idea, Toni. I've never seen anything quite like it. The "old-fashioned" type that I have is very basic and requires the contents to be manually turned with a fork every so often. Even though it is off the ground a few cm's the moles still manage to get up into it to plunder the resident worms. :-? This model that you have is mole-proof! Which reminds me Toni...don't forget to dig up some earthworms to put in it. They'll work for you for room and board.
