I also went through 4 Naga Trinity's, useless build quality, one of them failed within 2 months, none lasted a year. Kept double clicking on left click or deselecting when i was drag selecting. The RMA process was pretty painful too, a far cry from Logitech. My previous few mice were G600's and they developed the same fault too.
I've now got a Corsair Scimitar Pro, bit annoyed to lose the mouse wheel left right click functionality but it was lose it or stick with Razer. I bought it through Amazon, luckily their returns are very simple as my first one had an issue with button 4 sticking. Hope this one lasts a bit longer than my previous mice!
