Are you still banging on about this?Right, I'm going for a wired one. Slomo's bellpush has inspired me. I think I covered the hole when I decorated the porch so I'll have to push a drill through it again but as no one has dazzled me with a wireless one I think I'll bow to wired inevitability.
Let us know when you want a recommendation for dishcloths or dustpan and brushes.
We're happy to help.
