Had this mousepad for nearly 2 years now – it's been used virtually everyday in online gaming and it has lasted very well! (That said, I think I need to purchase a new one). Works very well with gaming mice that use PTFE feet (like the logi g5 etc) although the side specifically designed for ballmice seems a bit redundant. Would have been much better if they'd perhaps made both sides the same – that way you'd get twice as much use out of it on your optical/laser mouse.
Very good, very durable pad though. I recommend it to anyone who's thinking of making the jump from a cheap pad to something a bit more orientated towards performance.
