Ugh, more problems with the mouse. Heard they break so easily. Ordered mine today after much research. Kinda wishing i'd gone for the Lachesis.
I have had my copperhead for a year now and was happy with it until recently.
I was having a shocking game of tf2 and noticed that my left click button wasn't clicking until the button itself was almost on the mouse, and over the last week it got to the point that the button wouldn't click 100% of the time because the action had got so low.
I couldn't get the button off the mouse but I have managed to determine the problem and fix it. Seems the genius that designed it used very thin internal buttons and a soft plastic for the actual physical button you press. The result being the button on the circuit board wears a grove into the plastic button, and since the plastic button is larger than the pcb it gets to a point where the plastic button touches the pcb button surround so it can no longer press the pcb button down.
I managed to pull the button out far enough to fill the ridge with cyanoacrylate and and hoping that lasts a bit. This is a problem I have had before with mice, but usually after 4 or more years, bit cheap it did this so soon!
