I realy cannot believe you couldnt find the fault with 181199 , the left and right click dont work right, i sometimes had to click three times in games to acauly shoot
If you do get the chance to doulbe check, do exactly what i did, Open CSS, get out a pistol and spam left click to fire.... and now do the same with any other mouse. You'll see what i mean.
I know this sounds a bit harsh, but I'm realy not impressed that i have to now be charged
