I use Rival 310 as well :D very good mouse for big hands.
i don't know you'll do this but i wanted to give a suggestion. you can replace the clicks by buying "Omron Mouse Switches" from aliexpress, or you can but it from Canada if they sell those switches.
I think this is the switch name and model: Omron D2F-01F
It's pretty cheap. You can also watch the tutorial on youtube, by searching " Steelseries Rival 310 mouse switch replace/fix" if you don't know how to replace the switches. i think tutorial videos of other Steelseries mice will help too.
It's very bad and shame that users had to fix this "mouse click issue" that SteelSeries and other gaming mice has.
When I bought this mice 2.5 years ago, after using it for like 3 months, double click issue happened at left click. I fixed this is by clicking hardly to the left click for like 1 or 2 times and since then, i didn't encountered any problems with the left click or other clicks, i know, this fix is very, very absurd :D I never encountered any problems with mouse clicks when i was using regular, cheap office mice unlike gaming mice and the irony is, i was using Rival 310 very gently unlike the cheap office mice, i wasn't using the office mice that gently and still office mice were very durable and i used them for years but A4 Tech X710-BK wasn't like that, it was a gaming mice and it was very durable, i used it for 6 years, and i bought it as "used", it served me very well for a very cheap price, it was less than 10 dollars i believe.
But I still can't believe that quality of the clicks are trash on gaming mice.
I hope this essay helped you!
