Hi, My g502 HERO has started to double-click, I do not know if it's under warranty but this is the second mouse I have used that has had this same problem. I purchased this mouse 8/12/19, which means in almost 1 year my mouse has gone bad... again. I hope you will be able to help me resolve this issue, or I don't think ill be using Logitech gear again. User's recommendation: Avoid Logitech if you worry about long-lasting products.
