No experience with that model in particular - in fact, I don't even know whether it's a mouse, keyboard, speakers or whatever else. But I've noticed a trend with Logitech in the past five years or so -- their product quality has gone way downhill while their customer service has gone up, to the point you feel like you're getting a rimjob when you call them. In essence, it's cheaper to make ultra-cheap products and replace not all the ones that break, but only the ones that break which people contact them about than to make a quality product in the first place. After having a number of their mice fail me within a few months each, despite the great customer service, I switched brand affiliation to Razer and have had zero complaints. Even though Logitech replaces its failed units and picks up the shipping, I'd still rather not be bothered contacting them and going peripheral-less until the replacement arrives.
