Questions about Razer mice

I've had Razer Nagas for awhile now, I love the thumb pad with numbers. The issue is, they've all been shit. My current one is the Chroma and the left click button cracked and broke off. My previous two regular Nagas just quit working router login....If I like the number pad of the Naga, but am tired of replacing mice within one to two years (the Chroma Naga is only 6 months old)....do you all have recommendations on something very similar that might be more durable? I've been waiting for their support to contact me back, and it's been 2 days. I'm pretty much over Razer at this point.
