I have had a Razer Goliathus mouse-mat for some time now and it had started to wear and was quite unresponsive in parts, so to continue my use of Logitech purchases, I got the 240 mat. It's thinner and smaller than the Goliathus and amazingly smooth. It is extremely responsive with my G502 Promethious mouse.
I'm glad I bought it, and I would recommend it for other gamers out there.
Amazing product but I don't think the price fits it well(not a huge problem as it is still fairly cheap). I'm guessing you're paying for the Brand but who knows? Other than that the product is amazing, feels smooth and grips to my table nicely! My mouse is very responsive on it and it doesn't cause any kind of flickering you may find in some other, cheaper, mouse pads.
