Question about Logitech M330 Silent Plus

the plus doesn't know. i've been using this mouse for a few years now and it's perfect. it lasts a long time and because it's wireless usb it's also very fast and convenient because you don't have to have a cable all the time. you can even hide the usb slot in the maize under a flap. it's also very pleasant when gaming because it's very hard to hear the "click".
