2003: TVS Ball mouse, still is good. Those switches were epic and I believe the micro switches too. 350 rupees.
2005: Samsung Optical mouse, 300 rupees. Still powers on, scroll wheel dead.
2007: Logitech G5. Hated it from day 1, size, shape, weight, everything, sold it within a month. Later heard that it died after 6 months. Rupees 2500.
2007 end: Logitech G9. I loved it form day 1, still works, but those Omron micro switches are infamous for their double click on single click problem. Anyway, it at least never died, and I'm sure it won't. 4650 rupees.
2012: Corsair M60. First unit had weight coin broken, replaced, second unit same. Now it's dead. Going to Kaizen tomorrow. 3350 rupees.
That's my mice history. PSU, RAM and SSD might be Corsair's forte, but mice certainly is NOT. There are plenty of reports of mouse going dead over Corsair forum, and now I'm one of them. I'll get a replacement, but I don't know what gaming mouse really is there which is flawless, I mean flawless in quality, not sensor wise. After using these Avago laser sensors I just too much like them, I don't like optical sensors. I'll never buy Razer and those Steel Series craps (and Roccat) to be honest, if anyone knows a good laser gaming mouse do let me know.
Btw, just purchased a Frontech optical mouse for 180 rupees, it's good to have a 'working' or 'undead' mouse.
