Mouse wheel button.

I was a long time user of Razer mice but after breaking the Mouse wheel for the 4th time I decided as much as I liked them I was just too heavy handed, so I switched to a different brand swinging from Logitech to Corsair and back in pursuit of a mouse wheel that didn't feel like a snide comment and a filthy look would reduce it to a pile of plastic and dust. Recently I decided to come back to Razer after reading some favourable comments about the Naga and opted for a Trinity, as soon as I started using it I immediately felt like I couldn't trust the mouse wheel button, am I alone here or do others feel the same? Don't get me wrong I love the mouse but the wheel just leaves me in fear of another expensive piece of broken mouse tech decorating my room.
