Tried all the others and this one is the best. It uses very little CPU and fits perfectly up in the menubar looking just like it was meant to be there (put there by Apple itself). The preference interface is pretty clunky and there could definitely be improvments made there and in the dropdown menu gui. But, this is the only one I use anymore. Love the radar image (which the dev of weatherdock REFUSES to add) and once again, stable... doesn't use up CPU. The best.
