As far as I know the 'endless water' pitcher still works. I have used it for Gardening now for the last few weeks. Also in another house I use Hort-O-Matic 2 and it has a water trough in front of me and a water pitcher in the work container -- so it also seems like an endless supply, as the water in the water trough continues to refill the water pitcher.
