I was very lucky with the Logitech M555B (bluetooth) mouse. I always used rechargables, which meant I had to replace batteries every 2-3 weeks; but it was a great mouse for me. I didn't wanted wireless mice that needed their own USB port for the receiver. I guess they hava a more reliable connection, but since I already had bluetooth headphones I don't want more devices near using the same frequency with different protocols.
