Well, the Caspian KWC leaves a few things to be desired, if memory serves me right, we had try one here, but were rather unimpressed with it. Caspian told us, back then, that there would be a new model coming, but never seen it.

As for the BBs, that's easy, the twins love to collect them from the garden, so all I have to do is let them loose to search for them. Whatever is left, is taken care by the gardener (my wife).
