Bought a Logitech G502 HERO Gaming Mouse from an authorized seller online. bhphotovideoIt starts having double click problem in left and right click after 6months. Contacted Logitech and was told there's no international warranty.After researching , I found there's alots of quality issue with Logitech products. My fault from not doing researching..This will be my last time buying from Logitech. Poor product and support.
