I also use the pedros one, definitely something you'll want to do outside

. But it works well. It helps if you shift it into different gears to get the chain moving across the different chainrings / cogs, clean 'em all somewhat.
I just put the tip of the bottle of lube against the top of the chain, then spin the pedals backwards at a nice rate and squeeze the bottle... since the chain is moving past, the lube gets on all the links.
