Query: it sucks

i have bought several of these mice, and to be honest every time i am in the heat of battle it fails one way or another. it always becomes unusable and your settings will change mid game. try to ask for help and they ignore your requests. i have ended up throwing this product against the wall now it will be 6 times. to be fair i like certain things about this mouse and thats why i keep trying to give it another chance. but recently i asked them to help me with it changing settings mid game, and of course no response and when i was in a very important on line match it failed and became worthless.i checked the settings i made and they were all different then when i started the game, they had resset themselves to the maximum.
