Doesn't make it a good mouse mat (highfive)
Definitely not here to troll. Well you have it so know more about that than me, I have a g305 and g502. Pity that the 203/102 is bad on hard surfaces as you say, I would have picked one up at some point for an addition considering it's value for money. Hopefully the g502 wireless comes down in price at some point because I can't stand the rigid wire on it.
Expensive mouse mat!
Bad mouse mat (y)
But it's not. Not sure if you're trolling now. I have the mouse right here with a fellowes mouse mat which it will not work on!
