Hey guys, I'm looking into changing my current SteelSeries Rival 100 to either the Rival 310 or the Razer Deathadder Elite. Are there any particular quirks, faults or niggles with either mouse I should be aware of before purchasing? My history with Razer (owned the original Diamondback and its relaunch some time back) is generally average/poor as they only seem to last 2 years...could be just my luck though. I like the shape of the Deathadder while quality-wise, the Rival 310 seems the more solid build (my 40 Euro Rival 100 lasted 3 years before the wheel started acting up). Any suggestions please? I use a claw grip when playing FPS and palm when casual gaming. Price wise in Malta, they're both 69.99 Euro...though the Rival does come with a free mouse mat. Cheers!
