I bought two Logitech G703 mice. Both had issues on the right mouse button, as in, when playing FPS games it ADSs in and then out while still pressed. Makes the game unplayable. I bought one mouse in late 2019, 10 months later I had this problem. I bought a new mouse and ten months later I have this issue again. I wrote for support, took about a week to get back to me and mentioned nothing of the warranty - just gave really long winded instructions about how to check if the mouse works.
