I love this little mouse, it’s lasted me for 3 years and Amazon UK are selling them cheap right now at £30.04. It comes with a Bluetooth dongle which is pre-paired, but if you already have Bluetooth you don’t have to use it, it will pair like any normal mouse, and that’s a big bonus. MS’s recent mice all have custom receivers and I don’t want that, I already have a Bluetooth receiver in my laptop, so why on earth do I want something hanging off a USB port?
Anyway, highly recommended at this bargain price.
